I had one done at 14 weeks and found out I was having a little boy! When I was looking for one i just googled it and found one close to me. Here is the results for the google search in your area.
The one I went to determines at 14 weeks as well. Looks like in St Louis there aren't many choices. I looked at their packages and this one looks like the cheapest. $60.
