MT4 Coder for longterm cooperation

I’m searching for a new coder to repair, clean and improve an existing EA. My annual coding budget is about 1200 US$. I think I do have about once a week a coding request. Its important that coder is ready to work at least 1 year with me. For small updates I’m willing to pay 5US$, for regular updates 10 US$, for bigger changes 20US$. For the first job to find and repair a bug that stops the EA to enter im willing to pay 30 US$.  I always need the uncompiled mq4 file within 3 days after payment. Would you be interested to work with me? PS.: The code is quite complex, about 10000 lines.
