You broke my heart =)
Anyway, I wish you Good Luck with prestonames and in general ( I got it just now: you called it "presto" like speed, but start post with "I am slowly working", ha-ha ). Domaining it's not a rush - from one point of view, but from other - things are shifting so fast, what works few years/months ago don't works anymore. So post domains on website/market before renewal come =)
So sorry, for me it's just not easy to focus. Just now I noticed thread location "Web Design Reviews".
One more exp domainer told me smth like "Marketing for domains is more important than Design", when I was doing a website selling my portfolio and logos for domains.
1-st There are get ready markeplaces + socials + forums (like this one) ... use them
2-nd If you still want to create you own ones, used best of the best as startpoint, as most of them are already made with worldclass UI/UI practices
IMO
Good Luck
