GAMS Coding project help

I'm looking for an experienced GAMS programmer to help me with a coding project. I need someone with advanced knowledge of GAMS and the ability to fix code that has already been written: it implements the partial equilibrium model, IMPACT, but it has errors in it. The timeline for the project is one week so experience with fast turnaround times is essential. If you think you can handle this project, I'd love to hear from you. Thank you!
