No apologies needed! I'm just trying to help you figure out what it is that you're looking for.
You seem to be gravitating towards a custom, but just keep in mind what I said earlier about knowing what you want.
You're going to have to specify a lot of small details for the build. Body wood, neck wood, fretboard wood, number of strings, string spacing, nut width, fret size, pickup locations, pickup style, active or passive, if active...what preamp, etc.
In the end once the build is complete, if it's not what you want you might have a tough time selling it or getting even close to what you paid for it.
I think the first step is figuring out how many strings you actually want. You've mentioned more than 4, a good 4, 11, and possibly something else that I missed. Obviously there is a big difference there.
I can't help you out with Prometeus, I've honestly never even heard of them and I'm a gear nut.
