Have you considered semi-private training. This will give you a few workout buddies and reduced cost personal training. Unlike, typical group classes, semi-private training still provides you with individualized programs written just for you and are usually limited to 4-5 trainees per coach, so you still get a lot of individual attention at a reasonable cost.
Call around to see who in your area have these options and check them out.
I'm not from your area, but I do know of Optimum Perfmance Training Institue which I believe is just outside of Baltimore. I know of them because I subscribe to one of their coaches, Neghar Fonooni's blog and her youtube videos.
Here is a link of a video that shows some of the women training at their facility. If it is the type of atmosphere you are looking for, perhaps it is an option.
