Build an Online Store

Recently I had my site updated & I have no time to make the necessary changes/fixes and or updates needed before going live. I need to have someone check, configure and do a lot changes. This should only take a few days if not less as a lot of the work is checking, tweaking & 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 the Google Base Data feed, Header Tags SEO, CCGV and a look at the Site Map to see if its configured properly. These are already installed - there will not be any add-ons installed as everything is done - I just need things set up to work properly and the errors fixed. I do 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, changing font, colors & wording, change the look to some things and to adding 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 if it goes smoothly to be completed on a timely basis (within a week or less) unless otherwise notified.
