Small WordPress adjustments

I purchased the AdForest theme from themeforest, but after the demo impport, the page does not look like the actual demo. This needs to be fixed. The demo ads are there, but they are not displayed at the frontend.

I also need the header modified (change background color, replace logo, add/remove some elements).

Please only make a bid if you can start right away and finish within the next 6 hours max.
