Hi, I am pretty versed in the Wordpress WP-eCommerce plugin as I built this site http://oaktreeave.com from ground up based on the WP-eCommerce plugin. If you need any work done (big or small), shoot me a PM or Skype (itisme1760). I charge fair prices, $5-10 for small jobs, and $25-50 for larger jobs. I am on my laptop almost 24/7 and can get your work done ASAP!
