Looking for a Zen Cart expert to install updates + add-ons and modify as needed

I'm looking for someone to update zencart from 1.3.8a to 1.3.9f. I would also like you to install zencart order manager, shipping estimator sidebox and aweber signup sidebox add-ons. Additionally, you will need to change the RSS links to feedburner. You will also be required to remove and update some other add-ons. ## Deliverables Add-ons to be installed: * Zen Cart order manager - [login to view URL] * Shipping estimator sidebox - [login to view URL] * AWeber Signup Sidebox - [login to view URL] Changes to be made to existing add-ons: * Change RSS links to feedburner URL - Currently using the RSS feed add-on - [login to view URL] Add-ons to be updated: * Ultimate SEO URLs - [login to view URL] * Newsletter Subscribe - [login to view URL] - if this is a conflict with AWeber, then I want AWeber instead. However, notify me BEFORE removing any of these files so that I may get my existing list. Add-ons to be removed: * zen cart translate module - [login to view URL] * follow-up autoresponder for zen cart - [login to view URL] The site which you will be working on is: [login to view URL] This could lead to future work. I have over 30 WordPress sites and I'm looking to build another ecommerce site. I find myself needing the assistance of an expert coder more and more.
