you might consider local fabricators rather than small batch manufacturing.
particularly for your personal purposes.
If your quantity is low, say less than 5-10 you should contact a woodworker, metalshop, upholsterer - whatever you need done and just pay them the peice price.
as you say, with no training or experience you have a uphill climb getting these onto a sales floor, (or getting you into a job). Small businessmen will be willing to spend time and talk over your designs with you to get something they can make easily - not something your likely to get from China.
