There's a guy here said that he has 7 Years of experience in C, might want to try to contact him
https://bitcointalk.org/index.php?topic=3156060.0Do mind that he is a brand new account, be cautious and use escrow if there are money involved here.
On the other hand, I might be able to help if you can tell me what you needed exactly for
Word of advice, do not suggest other people unless you are absolutely sure they are what they actually said they are. That guy could be an utter noob and you wouldn't know any better. Worst case he'd try to get the job done and run with the money. Even if he does refund the money, the time he'll waste could be invaluable.
I have project about Dash. Anyone can be a part pls left message here
I know a few devs that I can vouch for. But you would have to explain the project in detail or at least the gist of it first.
