Based on all factors, I think this would be appropriately valued from low to mid $XXX undeveloped. If you found the right end user, this could sell anywhere from the high $XXX to low $X,XXX.
Factors I based this upon:
The listed sales for .pro domains with well-known keywords have not been too impressive.
It is unlikely to receive type-in traffic since the extension is not well known right now.
It can be branded well, but the keyword length is a bit long.
The extension fits with the keyword well.
Your term is very generic, which makes it appeal to a broader audience, and thus potential end users.
Congrats on a good, solid name!
