Offering your testimonial for one of their products you
have purchased and benefitted from is a logical next step.
Then you can become an affiliate and promote that product
to your list of prospects.
Going through this process slowly and carefully lets this
person know that you are serious about your business, and
understand the appropriate way to build a relationship.
This is not so different from what you would do in person
with someone you wanted to get to know and do business
with. The fact that you may not meet them for months or
years only means that you must make the effort on the
Internet through those channels of communication.
Once you have moved from prospect to client to affiliate,
take another look to re-evaluate the process. If this is still
someone you want to do business with, reach out to them
with an email to their support desk or even a letter to them
at their business address. You may want to ask them for an
interview at this point. They will let you know if this is
something they are interested in doing. At no point should
you ever feel that they are obligated to do this, simply
because you are a customer and an affiliate for them. I
have found that meeting them in person at a live event will
accelerate this process.
