MXL timing belt should do that easily. Some design guidelines for timing belts here: http://www.sdp-si.com/D265/HTML/D265T042.html
They say the "mini-pitch" (which includes MXL) belts can go up to 10000 feet per minute. And an MXL pulley can be as small as 10 teeth. You can (and should) be more conservative than that. For example, use a 30 tooth pulley on the motor and a 15 tooth on the load. The pitch diameter of the 30 tooth is 0.764 inches, so its circumference is 2.40 inches. At 7000 RPM, that gives a belt speed of 1400 feet per minute. For a light load, a 1/8" wide belt would probably be plenty.
