There are many internet sites selling flash templets, just google flash or use your search. Most flash programs are quite costly. Without a progeram you will need to contract a flash web builder to build it for you.
If you don,t have a flash program. don't bother trying to build a flash website. Most flash elements can be added to any website. Be careful
when buying non suported templets. There are many charities that could better use your money.
