do modifications already exist for these requests?

[iPrecisionNET]

I recently convinced a client to switch from phpBB to vBulletin and he has been very happy with the change. My problem is that this morning, out of the blue, I recieve an email with a request for a bunch of changes (when I strictly said it was an install and color-theme editing only). Does anyone know if mods already exist for these requests? I did a search and didn't find anything, so I figured I'd post to see if anyone else knew of something I might have missed;

1)New icon for newly posted items &/or make forums bold when new posts have been made.
2)Bolden, and make new color for Moderators
3)Bolden, Italicize, and make new color for Supermoderators
4)Bolden, Italicize, and make new color for Administrators
5)Add sponsor banners to sidebar for main forum
6)Create scrolling sponsor banner below soon to be made forum header
7)Create top and bottom banners for advertising site sponsorship

Some of them seem rather involved, while others seem rather simple. I'd rather not go editing the php myself if its an already beta tested known-to-work-properly contribution available. Thanks for anyones time and sorry if the search function wasn't so friendly with me. (it actually crapped out while I was still searching).
