$1000 - depends on when. i would either buy content for 3 kickass avs sites or shoot 4 models.

$10000 - get a better camcorder, pay shock to be exclusive for three months, get 3 nice (not wonderous but nice) computers, buy advertising.

$100000 - blow the muscle site into a total non nude site, with articles and what have you. maybe a print version. start a female muscle site to go with it. start a non nude program for webmasters featuring several sweet niches - and 100% exclusive content.
