help needed on modern to DND game

[nytflyr]

Im looking to start a game where the characters are all in the modern time, specialists who are hired to recover an artifact fomr this ancient temple in China. when they leave the temple they discover they are in a different world.

how would you go about building the classes?

class examples:
Tomb Raider
Soldier
Stuntman
Cat Burgular
Big Game Hunter

or is there a generic "modern" class out there?

If you want straight D&D conversions, just don't allow any class with spells. That works too.
