Sounds like a great opportunity. As someone alluded to you need to clarify if you are going to be able to log the hours as P2. Many corporate outfits operate their TP's with multi crew for insurance requirements although the AOC may list it as a single pilot aircraft. Therefore you could find yourself in a situation where you are effectively acting as safety pilot and not as a co-pilot logging P2 hours. Problems arise later on down the road when you are looking for your next job and have to explain to a potential employer how your hours are so low but you are type rated.
Regardless of the logging issue if the type rating is free then I would say take the bull by the horns and get some commercial experience and dive on in.
