Any suggestions on how to account for contractor to contractor pricing variation?

Up to 5 units for $25 a month to start out, after the free trial is over.

you dont assemble a team and then start investing.you start investing and then you assemble a team by trial and error.what's their incentive to be on "your team"?

I put my first-ever yellow letter in the mail today to the owner of a property I found while driving around town (driving for dollars). I wrote down the address, went to the county clerk's website and found documents ...

But DFW is a large area, and there are great variations by neighborhood.

I was looking into doing something similar and either using a CRM (lots of free ones out there or with good trials) or combining a Google Sheet with an add-on for mapping, so I can look at the list by neighborhood.I got the idea for the free CRM after Googling and finding a BP blog post that talks about the same exact thing (https://www.biggerpockets.com/renewsblog/2014/02/1...).  

The direct approach (asking) demonstrates your ethics and as the variations are typically "fill-in-the-blanks", I would venture you would get the consent.

Buffalo, NY doesn't have a ton of wild pricing variations so I just threw in the 100K number as an example for our C-area .

Those materials are outdated and come from someone who hasn't wholesaled in year, if ever.They all tell you to do the same stuff with a slight variation - letters, yellow letters, post cards, band it signs, etc. 

I really learned a lot since making this post threw trial and error.
