<other company name> has long been a respected presence in the <other company’s industry>. That being the case, I feel it would be in the interests of both our companies to agree to exchange business referrals. <description of business relationship.>.
I would like to set up an agreement where we would refer appropriate business to each other on a regular basis, but not exclusively. This could be highly beneficial to both companies’ bottom lines. If you’re interested, please give me a call at <phone number> and we can arrange a meeting. I look forward to hearing from you.
