Not has much work has you may think, profile still has to be drilled, tapped etc and it's not always easy has folks think it's shitty stuff to drill and even worse to Tap good threads into.!

(looking more at costs rather than exact setup at the moment)
The best way is to use 15mm HTD timing belt and pulleys running around 2 idle bearings to central motor.
Your local bearing company may be the best place to ask, I use lots belts & pulleys and this what I find cheapest. . . . But failing that then there's likes of Bearing boys etc on-line. If you look around the forum others have posted links to places they've bought.
