The domain iqine.com (5 letter, non-pronounceable .com) - Low hundreds, up to mid hundreds
Findrt.com (sounds like find art, but isn't) - If findart.com, I would appraise high thousands, 5 figure territory. I want to suggest high hundreds, but tricky. Need to sell it hard that its a quirky way of saying "find art", the quirkiness of it can give the impression the stuff you find is different - Quite like that
The others...not so thrilled. Relatively low value, in my view
