Hi Jaratvit,
I am also getting ready for my first launch. I come to the IM world with plenty of experience as a Management Consultant, but zero recognition in the IM world. What I did/am doing was to send a letter to potential partners detailing my product and its bona fides, and then asking them to do an interview. I had purchased materials from all of them so that helped with the introduction.
Since I have no recognition or list, I knew I needed to use the "reflected recognition" of established IMers.
After I did the interviews (by the way, I got 10 well-respected folks to do an interview) and we had at least some semblance of a relationship, I asked if they would like to JV with me. I have positive responses from about half so far.
The point is, you need to start early and be prepared to have patience as these folks are busy and much sought after.
I also wrote the base copy for my salesletter and will have a pro look at it for final tweaking. That is a way to save some money as they do not have to start from scratch.
I also realize that there is a lot I do not know about this process, so I "hired" a couple of partners to help me through the technical and structural aspects of a complex launch.
If you want their contact info, please PM me and I will send it along.
Good Luck,
Jim
