Like Mattiac stated, it may be tough for us to tell you exactly what to do because there are a lot of variables invloved. An option though would be to get an adjustable draw length bow that would cover maybe a 29-30 inch draw. Darton (as well as others I'm sure) makes a bow that can be adjusted in 1/8 increments across a pretty wide range of draws (without changing modules). Maybe start by doing some resaearch and asking specific questions directly to manufacturers concerning your needs.
