We've found probably enough candidates through agencies that look like they'd do for us, I believe. Wifey has a 3-day weekend this weekend, and has volunteered to compile the spreadsheet of the candidates, print the emails I've had with agencies, etc. We're strongly expecting that we will be able to pull the trigger early next week and tell one of the 3 or 4 agencies that we're repeatedly talking to that we want to go with their donor in particular.
BTW, the actual donor fees are higher than I'd expected, for the private agencies that don't have a DMV "take it or leave it" attitude such as the university teaching hospital programs seem to have. Looks like more like $6K is what a donor could expect to get paid by us for her time and trouble (not counting transportation, nice motel, meals, etc.) while in N. TX.
Oh, and if anyone knows a potential donor that could use that amount of lawfully-acquired money towards her education, starting a business, getting a bunch of preps, improving her family's land, health care costs of someone in her family, or (IMO best of all) towards starting her own family with her husband, the possibility is still there for now. I rather like the idea that that amount of money would go to someone at least connected to the prepper community.
(She could even be paid in PMs, if desired.)
