Need Oscommerce 2.3.3.4 - Configure, Checked & Updated

My site had been updated & I have no time to make the necessary changes/fixes and or updates needed before going live. I need to have someone who is familiar with OSCommerce to be able to check, configure and to design & make changes to the site before bringing it live. Again, a lot of this work is checking, tweaking, updating & make sure things are configured & set up correctly (and WC3 complaint). I will need to have a few things configured (or it might need to be updated to work properly I don't know you would be the expert on that) for me such as setting up the Google Data Base feed, setting up and fixing errors in the site and in the Header Tags SEO & CCGV and look over the Dynamic Site Map to see if its configured properly. These add-ons are already installed - I just need things to be looked over and set up to work properly and any errors fixed. I have a list which does look long BUT keep in mind it is mostly very very simple things to do - as in checking to make sure everything runs & is working properly before making the site live, doing updates & tweaking things, such as making design, color and font changes throughout the website and again just checking to make sure that things are correctly functioning. I need to also change the look to some things which a lot of this stuff is simple changes to the [login to view URL] and adding some words and adding other things to the way the Checkout and Login look to make it look a little smother and nicer etc... it is a lot of tweaking that needs to be done so I will need someone who understands how to do this & will be patient while we do this...time is not a big thing if you need it as I want it to be right. Before applying for this job PLEASE PLEASE you must be able to communicate with me and understand & speak English and I want things to be completed on a timely basis (within a week or less) unless otherwise notified. Keep in mind that I would like to be able to hire someone that would be interested in doing more work for me in the near future. Madison....
