Customisation of 9gag similar site

Hi all, Im looking for a developer who can make some changes to my site. Basically I want to add a 1. picture banner and include. 2.a twitter chatroll for this 9gag clone site. (I have the twitter widget code for this) For the experienced php developer, this will only take a short while, just a few lines of code plus cutting and pasting of the twitter wideget code, which i will provide. I will need to know what are the exact changes for this implementation, because the last developer did a bad job and I wasnt able to just reverse the changes, in the end I had to reset the project. Project last quote is 40 USD but I need this done over the weekend, so I am giving this project to anyone who can work on this fast. Payment upon work done, no negotiation - clear cut. If the work is done well, I will top it up with a bonus.
