Need Wordpress help, Familiar with "WP e-Commerce" shopping cart plugin required.

I've recently taken on a job of helping some local friends and her business associates fix a website they are soon to launch.
The original designer put most of the site together, and then somehow broke a lot of the links pertaining to the shopping cart.

I am outsourcing this work on BHW because I am not familiar with the plugins being used and would rather secure this work with
someone much more familiar with it than myself.

Qualified applicants should posses strong Wordpress skills, knowledge pertaining to the WP-eCommerce plugin specifically, and be willing to sign an NDA (non disclosure agreement)

I'm looking to find the right person to investigate the situation and give me feedback on what exactly is found wrong and what the time and cost involved would be in fixing it.

If you think you can do this, PM me for more info and a link to the site in question.

I was told a PERL find and replace script would be a solution to the linking issues, But I don't know to what effect or how accurate that is. Any info pertaining to this subject would also be relevant.

Mods can delete this.
