If you haven't built a quadcopter yourself yet, I *highly* recommend basing your design on an existing kit.
Also, are you sure that brushed motors are the best option? Most quadcopters I've seen use "brushless outrunner" motors, which apparently weigh less and run faster. Also, the ESCs that control those motors are specifically designed for brushless motors.
It's unlikely that someone will download your entire kit, open it up in Eagle, and then start trying to debug it for you. That's a lot of work, and you're not making it easy for anyone to spend their time helping you for free.
Anyway, the best way to get involved is to just build it, and then figure out why it doesn't work. Unless you're starting with a proven kit, plan on the first one being entirely thrown away and replaced by the time you get to a working solution, so make sure you have at least 2x the budget of what your first kit costs.
