Help with Link Building

I have 2 new websites, naughtycamshow and xtremeadultlounge, and was wondering the best ways for advertising and link building. Ways that are not going to break me. Anyone have any suggestions?

Try guest blogging, create free blogs on sites like wordpress, blogger etc., with unique content and put links to your site in the content, join adult forums put link in signature and start to write posts, make comments on adult sites, blogs with a link to your site and stuff like that
