For some months now I have been working with a solar company who services both the wholesale market and the retail market when I first came they were just starting in the retail (When I say retail I mean they install solar panels in residential homes), since then I have successfully generated a ton of leads for that business.
A couple of days ago I got a phone call from the owner saying
"We've been really impressed, with the amount of leads you have been getting for our business. We are inviting all our solar clients, and potential clients to a seminar we are hosting, and would you be interested in talking about marketing online?"
So I prepared a quick slideshow wowed the audience with my presenting skills and afterwards sold $10k worth of web design and local seo services.
So I guess the moral of the story is to try and find as many clients as possible who do both wholesale and retail!
