Sounds like you have the talent, skill and inspiration. Can't tell if you have the technical background / education. If you have that, then all you need is time, money and test equipment. Quality reference units would be a help too.
If you have never actually built a piece of equipment before, I highly recommend you start with kits, as others have said. You may even find that they give you all the satisfaction you are looking for.
