Remember from what you have studied these last two years - beyond the potential legal ramifications, all you really bring to the deal is your reputation  (you already fear that a simple check would blow that - and the deal).  

I am working on setting up our first direct mail marketing campaign and I was wondering what recommendations the community might have for direct mail yellow letters/post card suppliers as well as what answering services you have found to work best.  

Most the reputable property manager companies id recommend (although they've never managed my property I've dealt with and know many people who have used them) would prob be Howard Smith or Paul French.

Must have references/good reputation.

Taleb said it better than I ever could: “Odysseus, the Homerian hero, had the reputation of using guile to overcome stronger opponents.

A Google search shows numerous possibilities, some that charge as low s $40.Not sure who is reputable and was curious if anyone has used any of them before that are reliable?

So, tell me I'm not the only company that has had a supplier place liens on their properties because  the contractor who worked on said properties stiffed the supplier?

I've been using Smart Cabinets - Squire Maple - http://www.smartcabinetry.com/squire.php - from a local supplier.

If Online, are there some reputable sites that I can go to?

We are recently incorporated and I am more concerned with building a good reputation/portfolio than I am making extra profit.
