Website design / coding

I have a Urban network im having issues with, I purchased the site from the builder in ...I want to say in Nov '09 ..all paid upfront. Ever since, I have had issues, getting a hold of him..to finish the job...for the last few months..so i had to start looking into the whole html/ccs coding etc.. So its all new to me, but i need someone to come in a rearrange a few things i guess they would be modules, etc... Like before I'm new to all this...Its running off of Joolma.. Its supposed to be a mixtape download site...where all our artist and djs can upload there zip file and covers, and it will auto post... here are a few examples of what it should be similar too.

If someone could please help, please contact me asap...with a pm ..our budget is tight, and loosing what i already paid the guy to do it set my funds back for the site...

I still would like to get a quote to see what it would be to finish the job, pm me i will send a link to the site, so you can check it out and go from there...

Thanks
BHW!
