E-Bay is always a good start. An Internet search for gymnastic equipment will give you loads of places. Try your local yellow pages (or yell.com) and local ads too.
My son used to go to gym class, they had big rolls for them to ride on the belly, carpet and mattress protection, pommel horse, trampette, beams, benches, stepping stones - all sorts of things. Tell gyms in your area and see if they gym sessions for children or they may be able to give you some tips on what to include.
