Project Description:
Hello

I'm looking for some GOOD pre-existing auction software written in PHP. The budget is more like $500 - $2300.

You must own it obviously, and give me full rights to do whatever I want with it.

I have two coders, but before having them create one from scratch, I want to see if there are any good ones already ready to go.

I'm hoping to find one that has good clean, commented, secure, well structured code, that has been de-bugged for the most part.

Also hoping for it to have many of these functions below, along with being able to make it a reverse bidding script like freelancer.com, so it could be used for projects rather than items, so the script will be more versatile. I got the list below from rainworx.com (all of these functions are not mandatory, but the more you have the better):

I would need to see a demo of the script, and would like to be able to have one of my coders look at at least some of the code to see that it is written well.

Thanks
