Because of an unpaid debt, I may be able to acquire a hodgepodge of over 4,000 currently registered domain names, for just the cost of transfer. I have no idea if any of them are valuable enough to even bother.

However, I am able to freely "cherry pick" from the list and acquire only the ones I want to resell, or I can take all 4,000+.

What is the best way to realistically sift through 4,000+ domains to select only the ones worth the candle?

Also, what's the cheapest method of bulk transfer? Thanks!
