I Need Some Suggestions Please.

I love the current layout I have but I'm finally getting into the groove of things with my blog and would loveee some suggestions on who and what websites you guys used to have your blogs customized.

I think it's finally time to really customize my little part of the interwebs. Hopefully soon, I'll be able to have some sponsors as well, there are so many great blogs that I would love to show off!

Any help would be much appreciated, thank you!
