Reciprocal Link Building:Contacting webmasters of relevant sites requesting for have a link exchange. Write personalized emails to request for link exchange. It will be better if you write 2-3 good things about their site and tell them how link exchange will benefit both parties. Also, mentioning good qualities and PageRank is always good idea.

Do not forget to ask and give (1) URL of link, (2) Title of link, and (3) Description of Link.

Now, main thing is How to find good link partner. Search google and other search engines for terms like: “keyword reciprocal links”, “keyword links”, “Keyword link exchange”, “keyword link submit”, “Keyword link partner” etc.

I came across few tools for searching link partner:

Link Partner Finder - from 4th media.
Find Link Partners – from zebonline
