Setting up Facebook groups, a Twitter micro-blog feed, Stumbleupon, Digg, Delicious etc and adding daily content, then inviting others sees audience grow and links to your site. Raising awareness with some video and making usre you add your http://www address in the first line of the summary on your YouTube etc posts will give you clickable links to your site.
Online PR is excellent for growing links, and if it's really interesting, then of course it will be picked up by other online publications and bloggers and be well worth it. PRweb's introductory offer for new accounts at $200 level gets you a discount of $60 to just $140 - it's a paid for, but well worth the money.
Of course whatever you do add an element of viral to it, so why not add a competition.
You can also, think about joining banner swap or popunder swap networks which are low cost and boost awareness and traffic.
Any help on top of this just say hi at http://www.MediaStarz.co.uk
