I need a PCB design made with RGB LED ring

Just a man with an idea. Updated: January 20th, 2019 I've updated this project description (again) to clarify a few more things and correct and earlier error. - Bids exceeding $250 will be immediately deleted. - This project is not intended to be mass produced, and I intend on making the files freely available. So I need to keep the costs down or it's just not realistic. I have a ve...

The purpose of this project it to build a very simple controller that will rinse liquid waste out of the cat litter box.
