inundated with real estate courses

1) Go to county offices + get (research) 100+ seller carry back notes (info). I did a test of this, just to see HOW to do it -- clerk told me a) seller carry backs are very rare (1 in 700, maybe), and it would take hours to come up with even one, and b) that others had come in to do the same thing, and they never come back because the research is so boring + disheartening. What *I* discovered is, yes -- it's boring, but I came up with about 15-20 per hour. So, getting 100 won't take THAT long after all.

2) Send a letter to the sellers who did the carry back at least one year ago.

3) Hope for some replies.

4) sell the discounted notes of the people who want to cash out + get my finder's fee (arbitrage).

Any idea how many letters I'll have to send to get ONE nibble?

Of course the overall goal is to come up with a repeatable system ("machine") that predictably generates results based on research, sending, and response percentages/ratios.

Any advice/input on this 'plan?'

Thanks!

PS: Time frame is to keep tweaking the "machine" so that I get SOME result(s) ($$$) by mid-August or sooooner!
