Create MAG AT NEWSSTAND

Hi team, 
am willing to publish a magazine at apple newsstand, 
any idea how i can do that? note that i have my magazine on PDF, moreover i believe you have your own designer to do that , is it true? how many days it take? and do you help me to upload it into app newsstand?
sorry for asking all of those question, but i have to submit this in a couple of day :( :)
Regards
