It [i]was[/i] Sidious' plan to create the Clones, right? I believe he told Dooku to find a suitable template as well as destroy a renegade Jedi. Dooku hit two birds with one stone and hired a number of bounty hunters to track down that renegade Jedi. Fett was the victor and defeated the Jedi, and was thus chosen by Dooku to be the template.

Sidious must have had a hand in it all since his intention was to form an army that was strictly loyal to him.

Also, I am not entirely sure Fett was always in it 'for the money'. I've always been under the impression he's been somewhat honorable. Sure, he was in it for the money at times... but Dooku paid him a handsome profit for not only killing the Jedi, but for being the template for the Clone army. I never understood why he felt obligated to assassinate Padme. He HAD money.
