Wordpress Expert Needed

Wordpress site issues: I get the "blockUI requires jQuery v1.2.3 or later" error on the admin side. I tried using the jquery updater plugin but that has not worked. Tried to get the twitter feed embedded into the template but had trouble with that. I will need the Twitter Feed on the footer, pages sidebars and blog. I also need 1200 comments deleted and a plugin added to stop the comment spam in the future. I am looking for someone to make fixes on other wordpress sites. I have a few sites I work on and need help if you are the right person. Please bid on the work above. I need this done quickly, thank you for your bids.
