Hello,
It will definitely be okay in a golf, just make sure that you support the bass around the heel of the neck.
As regards buying a bass, try Peter Tyler, he is in Maidenhead, Berks. Yes, I know it's a long way, but, he will be able to sort you out with something between £600-£20,000. He's a great bloke.
