For this question to answer you should provide more information. If I'd looking for a job, I'd ask myself first if you provide all graphics?
But I think you need a lot of luck to find the right person. There are a lot of C2 devs here, who have no clue about "real" programming and just make projects work "somehow". And there are masterminds who have an excellent programming style. And first one maybe even charges more than the other. It really depends on the dev. I think if you're really willing to pay someone, let the devs write you and make a little "interview". Let them program a small example capx and ask them how much they want to earn. And then pick wisely.
