Hi, with second name I can not help, but try to list onator.com on brandpa or brandbucket etc.
Wish you luck
P.s. I am quite new (started just four months ago) in this so you should probably ask older members.
Another idea. Maybe you can earn from traffic of onator.com from people who misspell donator. Did you tried to found out monthly traffic for that domain?
