I liked the idea of timing belts but where can I get it and its sprockets?

Gates provides some in the KOP.

There are also a number of ways to tension chain. One of the favorite ways is to get a cylindrical block of delrin and mount it by the ends, using an off-center screw or bolt. Rotate to tension the chain.
