I make my own basses - all custom builds, and I will share one bit of wisdom with you: You will NOT get everything right on your first custom build - there are enough variables that it's almost impossible, unless you have a very similar instrument, where you've tried out those things, to specify your dream bass.
You're on here asking for advice on things like string spacing. That means you don't know what string spacing you prefer. You really need to have important things like that figured out before you specify a custom build.
The way to get to your dream bass with the least time and money is to take something close to what you think you want, and do mods to it, until you figure out what you really do and don't like. Then, and only then, are you ready to specify your dream bass.
And yes, a Warmoth build is a good thing, but even those are more expensive than a lot of production basses that you can do mod experiments on - I wouldn't start with a Warmoth build until you have most of your stuff figured out.
