Looking for programmer to finish a job.

I am in the middle of doing a website for a customer but my programmer all of a sudden just dissappeared and I haven’t been able to reach him for a week now. The site is due November 1.
What I need you to do is to basically make a user module with a login, a simple control panel and some search functions.
When people sign up they must pay a small amount so a gateway needs to be implemented in the sign up form.

If you are able to do this using already existing Modx modules/snippets and make the whole thing more dynamic than hardcoded, that would be a plus.

I myself have been using Modx for 2 years and look at myself as an experienced user, but I’m not much of a programmer.

Thanks for reading, larsb
