How about asking for link exchange on popular webmaster forums?
Create a WTB thread on NetBuilders, DP and several other webmaster related forums.
BTW, if you don't mind me asking, what niche is your website in?
In any case, link exchanges are of limited value and excessive link exchanges can get you banned.
I think that it's best to deal one-on-one a get a few quality exchanges than to do a mass link exchange campaign.
