Reply to Custom Controllers

So, i am currently studying Audio Systems at university - a large portion of which concerns audio electronics.
I will be building myself a custom midi controller soon, not too sure whether i will be trying a cheap option with a hid device or go for a midi brain.

Once i have a few good builds behind me (Have just finished putting together a distortion pedal with an added tone control circuit) i was believeing of starting a small business doing custom jobs for people who want the functionality of a customised inteface, but don't have the time/expertise to build them themselves.

I have access to full workshops and the facilities to print my own PCBs, i was believeing of building a simple website whereby people can design their own controller with a simple drag & drop system of designing the layout (Ie. images of faders, knobs , buttons that can be placed anywhere on a chozen size and colour of faceplate), choice of in/outs and a way to label what functions they desire from each component. Then it would be built to their exact specifications, consulting them with images & info through emails at every stage of construction.

It's all a thought right now, and obviously since i am only one man with a limited amount of time i would be doing only one or two orders at one given time it won't exactly be a huge thing, but i believe i may be able to earn a few hundred
