The best marketers receive a multitude of requests to do joint ventures regularly. You must either create a new approach or have a unique selling proposition to get to the head of group.
I find that working at building relationships with potential joint venture partner's works best. You will need to make a connection based on mutual possibilities. You will have a better chance of gaining what you want if you proceed with integrity and offer to help them in some way.
Some ways to find potential partners:
1. Search on search engines for the niche you are targeting for sites. Review the results. You will get more sites to look at than you can possibly want to review.
2. Visit websites you already know in the niche and look for testimonials. Contact the people leaving those testimonials. Testimonials are provided by happy customers.
3. Ask your current partners, clients and friends for referrals.
4. Research the events going on - speakers at the events make great potential joint venture partners.
5. Research the social sites for possible groups to join.
There are multitudes of ways to approach joint venture partners. Send an email; follow it up with a request for a phone talk works well. Use your subject line in your email to your advantage. If you have anyone referring you, indicate it in your email.
You must expect rejection. If you do not receive a reply to your email, you have the opportunity to decide if you chose to move forward. Make an effort to review your potential partner's website prior to contacting them. Find a reason that makes sense for the initial contact. Showing your knowledge of their efforts and/or expertise will help open the door for discussion.
If you make a good approach and it just isn't going to work, leave the door open for later contact. Building relationships takes time!
