if you search namebio with sky at start, you can find some good sales with the term. Also, recently skymarketing was sold which i wanted acquire but it crossed my budget.
Hi
I see this time and time again
they go to historical sales site and lookup old sales using certain keywords
then, they go try to find unregistered names with those keywords that were found in some past sales.
what they don't ever get from it, is........ who the buyer and seller was, how long the seller owned the name, how many offers they got before it got sold and also the "times" at which is was sold, which is pertinent for many "trend" domains over the years.
still, it's not a bad domain, and i could see it having applications in the sky writing and banner flying space.
for incoming inquiry, i'd ask mid four figures
Good Luck!
imo...
