Please help - looking for skilled resource

Hi Guys, I have been working though a number of the people on WIX Arenas who say they specialise in WIX code and JS in their profile. I have paid hundreds of dollars to 4 different people now and after transferring a deposit and working though what is needed, they have all finally said its too complex for them and they are more designer than a coding expert. Is there any one who has real coding experience and understands WIX to help me develop some complex forms / data base requirements? Its taken me over 3 months to get to where I am and thats no progress at all… I guess if I can’t find anyone who is able to help, I willl have to change platforms… my customers deadline is approaching. appreciate if anyone can help for a paid job.
