Assignment of all rights / non-disclosure / non-compete

Does anyone have a link to a ready-made contract which specifies three things (in order of priority and possibility):

(1) assignment of all rights - so the employer owns all work created by freelancer

(2) non-disclosure - so the programmer cannot re-use or re-sell code, disclose ideas garnered between us (relevant to the industry or market we're working on), or tell my secrets to competitors

(3) non-compete - freelancer cannot just make a clone (at worst) of the site he's building for me and get a new domain.

These are all very important things and it's vital to get them out of the way in case of arguments along the way (where the freelancer might do something devious)
