Best of luck here guys...I am impressed at the way you've gone about this.
Couple of quick suggestions...gymnastics studios often already have mats, and often are looking to fill time slots. Cheaper than trying to go right into your own space. One group I train with occationally here in PA is in a gymnastics space right now, and as long as a LOT of little girls running around doesn't faze you, it's actually a nice place to train. Good for focus!
First time I've ever done aikido to really loud music...
Also, YMCAs will often make accomodations for local groups. Always good to check with the ones in your area.
