Do not do a link exchange! Google flat out bans them in their SEO guidelines (http://support.google.com/webmasters/bin/answer.py?hl=en&answer=66356). What you want to do is form business partnerships with other companies and help promote each other. For instance, a pet store and a dog walker have a real reason to link to each other (same target audience, relevant products/services). A pet store and a construction company do not have the same reason to link to each other. You want to build links from relevant sites!
