You may want to wait until myec plugs it in plugs it in, or you may feel very uncomfortable talking to the over the 59,999,999 crowd with a foot sticking out of your mouth.
I also think that the company should be doing its own sales. If you insist on doing this, you should at least become an independent sales contractor with myecheck and present yourself as such.
Unless you are a brother of the CEO of said #1 I would not send a letter. Again love your energy around MYEC but unless you have a specific link to said #1 I think it is a bad idea from a communication perspective. Again let ed and his team do this, apply for a job at MYEC but don't go rogue. Looks very unprofessional for MYEC. Great you have experience but apply for a sales job if you are so passionate so you can get trained on how MYEC wants to approach the sales process...
