Call a couple of reputable mason contractors in your local area for a good range of good work. They know the labor rates and the local requirements. They will not be as cheap as a friend of a friend of a friend.
If they don't bid it, it may be too small or just take you as a shopper. Good contractors rely on repeat business, but they might have some good employees that will do a small job while moon-lighting.
