Q: how to do a money music gig
A: get there on time, know your setup, dress how they want you to dress, know the material, and execute it passionately, within the guidelines required. and at the end if they forget to pay you, politely remind them. that is how to do the gig, not how to get the gig. the way you get the gig is someone recommended you after working with you on a previous gig, in which you did all of the above. i hope that makes sense
