Stock photo agencies

[Xander]

I have been thinking about getting some of my photos to a stock photo agency, but know NOTHING about them.
Can any one tell me:
1) a list of them good companies

2) what to "look out for" in terms of scams (used to work as a model photographer and there were more doggy people in the business then not).

3) best way to present your work (leaving this open to interpretation for a reason)

4) do they want Raw if not why not? TIff? or do they go Jpeg?


5) I have several gig (17gig) from my D70s (6.5m pix), will any of the companies accept this or does it have to be 10m+ or 12m+, is going through this back catalog a waste of time.

6) What about my slide negs do they accept these still? or do i have to invest in a hi-res slider scanner.

7) anything else that may be of use?

Sorry but like i said i know nothing.
