Hi, I need Blog Theme to do some things on blocks and admin options:

a) To provide a block, so users can choose their themes without visiting their accounts(sort of switchtheme), and,or
b) Add more options in admin settings: admin can choose how to show blog theme-themes list in dropdown, thumbnails list and show pagers (imagine a list of 100 themes).

I´d like to know how can I get in touch with current maintainer, payment schemas, hourly rate, how can we contribute back to community, and I can explain a little more what I need.

Thanks in advance!
