The no follows are more likely to discourage other sites to link to you. Link builders do watch for the use of no follow when considering who to link with. Therefore I would suggest you get rid of the no follow chicanery and simply go back to basics - get links from relevant sites and link out to relevant sites, reciprocating if necessary. Noone is going to link to a site that reeks of gamesmanship.
