Detailed Walkthrough
Overview
This quest is part of convincing each of the three Great Houses to name you their Hortator. The exact order you approach the houses in is not important. Again, you must visit all the council members of the House to convince them to vote for you. If you don't already have one, Nileno Dorvayn will supply you with a copy of the Yellow Book of 3E 426 which lists all the members, and for 50 drakes she will direct you to Crassius Curio. The members are: Crassius Curio, Yngling Half-Troll, Dram Bero, Nevena Ules, and Velanda Omani. Note that unlike the other two Great Houses, being the Grandmaster of House Hlaalu does not enable you to skip these steps.

Crassius Curio
Crassius Curio, downstairs in the Curio Manor in Vivec, Hlaalu Plaza, will support you for a little favor. If he likes you (70 disposition), he just wants a kiss. Otherwise, it's 500 gold for Hlaalu members, 1000 for non-members. Curio also has some good advice on the other council members. You get a +30 disposition increase if you kiss him, +10 if you give him the gold. Another option is to bribe him with 1000 gold (which will increase his disposition to 100) or a few 100s and then kiss him, bringing the price down and making him like you more.

Dram Bero
Dram Bero is hidden in the basement of the Haunted Manor in St. Olms Plaza. The basement door is locked (there are lockpicks under a table in the first room). You merely have to talk to him to get his vote. He'll mention that Velanda and Nevena are loyal to Orvas Dren, the brother of the Duke who has a large plantation in the Ascadian Isles (see below).

Yngling Half-Troll
Yngling Half-Troll is in Vivec, St. Olms Canton Plaza, Yngling Manor. He'll ask for 1000 gold if you're a member, or 2000 otherwise. An alternate route is to actually kill Yngling, which is quite alright with the other council members if you talk to them about it (such as Dram Bero). But beware; if you attack Yngling, everyone else in his house may come to his aid and help to finish you off. A good opportunity to kill him will provide itself during the Yngling's Ledger quest - refusing to give him the ledger will provoke an attack.

Orvas Dren
In order to convince Velanda and Nevena, you must take care of Orvas Dren first, which may mean a number of things. You can just kill him, but he is well armed and has a few good bodyguards. You can blackmail him if you obtain some papers from a   small chest in his basement (the two doors to which is   and trapped; his bodyguard carries a key, and another one lies on a desk next to the stairs directly below Dren himself, if you have a good enough combination of Chameleon, Invisibility and/or Sneak skill to steal it). Or, if you can raise his disposition high enough, you can talk to him about protecting Morrowind from the Empire, resulting in Dren giving you his vote for Hortator. If you're in House Hlaalu and you've done the quest to take over the Camonna Tong, Dren should just give it up and say he'll use his influence on his two puppet councilors.  Of course, if you completed that quest by killing him and breaking the link between Hlaalu and the Camonnas, rather than taking them over, there won't be a problem...

Orvas lives on the Dren Plantation, a large manor north of Vivec. If your disposition is low when talking to him, he may attack; kill him quickly to avoid alerting the guards.

There appears to be no way to show Dren's incriminating note to his brother, Duke Vedam Dren.

Velanda Omani and Nevena Ules
Once Orvas is taken care of, you can continue and talk to Velanda and Nevena. Velanda is in Omani Manor on Elmas Island, east of the Vivec St. Olms Canton. Nevena is in Ules Manor, across the bay directly west of Suran's House of Earthly Delights (directly east of the Dren Plantation, and northeast of Vivec). The manor is surrounded by slaves (there is no key to free them). Once you talk to each of the two councilors about the Hlaalu Hortator, they hastily give you their vote.

Return to Curio
You can now return to Curio in Vivec to be officially named as House Hlaalu's Hortator and receive the Belt of the Hortator as proof.

Notes
Although you don't have to talk to Nileno Dorvayn, her disposition increases by ten if you do. It drops by ten if you can't afford to buy a copy of the book from her.
Telling Orvas Dren that you wish to become Hortator to defeat Dagoth Ur will cause him to attack you, saving you the trouble of fighting his bodyguards.
You can start this quest before completing The Path of the Incarnate but will be unable to finish it, since there will be no Hlaalu Hortator topic in conversation.
