dareen, the best one to get is the one you are going to be offered work on, being as you don't know the answer to that question, best to do nothing. You are unlikely to be offerd freelance on a green type rating, even if the company/owner accept you the insurance probably will not. The market is fairly depressed at the moment and opportunities for new corporate/jet pilots are few and far between, you may well see your brand new type rating getting very old in your hand with no hours on it and needing renewal. Don't do it.
