So I'm always thinking of new ways to create passive income and wanted your guys' opinion on this.

The other day, I was looking at our marketing response and was impressed by the number of responses we were getting from such small batches of letters. This is mainly because we hand- address our letters and use real stamps so it looks like authentic communication. I've had sellers tell me that they opened mine because it looked like a friend sent them a letter or something. 

I wondered if other wholesalers/investors like myself would rather pay a service to hand address their direct mail instead of using companies like vistaprint, whose mail looks like any other junk mail.  The cost would be pretty close ($1/letter) and they would be getting a MUCH higher response rate.  I already have the means to mass produce these letters as I've been doing it for myself, why not extend it to my fellow investors?

1. Do you direct mail marketers think this is something you would benefit from?

2. How would you market this kind of service? I could somehow obtain a list of wholesalers and send them my letters. Once they open my letter, I'll prove to them first hand how opening my letter is indication that it will help their business!

Thanks for your time!
