Question about building on a Rem 700?

[Holyfield]

A friend of mine gave me a Rem 700 short action he had laying around and I want to build a 300 whisper on it but I have a few questions? First I have heard that the Remington 700 is not a good choice for the whisper because of extraction issues. I have no experience with this so anyone who has any experience with Rem 700's and the whisper let me know your thoughts. I want around a 16" barrel with a 1:8 twist and I would like to know if anyone can recommend a barrel manufacture and someone to do the barrel work for me. I am mainly interested in shooting subsonics with a suppressor and accuracy is my main concern with this project. Any information would be greatly appreciated.
