Hi Ken!
What do you need in a studio? How would you use the studio? Have you ever used or worked in a studio? I looked at your website and you have wonderful work! It appears your high end work is all outside. It's very different going inside.
My first studio work was out of a pro studio, great folks, great studio, decent prices, but 45 minutes away from home. I was doing fashion, and let's say the caprice of models made it a serious challenge to reserve and pay for studio space that I knew I'd use. I looked into the possibilities of time sharing with local small studios, and looked at converting part of our house into a studio. Converting. HA!!!! That's a joke. We are in suburbia in a 3 story townhouse with a small one car garage. We also have local zoning laws that until very recently did not allow for a professional photography studio in the home. I have unkind names for the municipality in which I live.
I'm not a pro photographer, however. I also have a small one car garage. That sounds like a studio opportunity for my situation.
If you have a garage or some space you can quickly and easily convert into studio space, and your local laws allow you to have professional studio space in your home, you're set. Also, if you have interesting space in your home, that's also potential studio space. Below is the link to my fashion portfolio. Much of the studio work was done in my little townhouse with killer gear: Canon Speedlites, a couple light stands, a C-stand, simple light modifiers, narrow and wide seamless paper and stand, and wireless remote triggers. I can shoot anytime I want. Yes I have to clean the garage floor whenever I want to use it, but that's okay. Models don't care as long as you're a good photographer and the space is clean, warm/cool, and safe. My municipality can say nothing because it's all for fun. My neighbors can say nothing either.

Ha! I'll never forget the look on one of my neighbors when I'd just finished a fashion session with a model. I was driving her to the airport. On the way out of our townhouse community I saw a family friend neighbor who "watches over the neighborhood", and I waved to her! Her jaw rather dropped as she could see the gorgeous young woman in the passenger seat was clearly not my wife. She and her husband didn't know about my fashion work. A few days later said neighbor was trying to pry for information, and I wasn't giving it.
I'd love to have space to have 40ft x 40ft space with 20ft ceilings, a full cyc wall, an 8 foot parabolic or bigger, huge soft boxes, black and white v-flats, et al. I don't. I watched a DVD based photography course that basically said the amount of space I have is wholly inadequate for a studio. That was my challenge. 
I get the idea of time sharing, but I also like the flexibility of having my own space when I want it. Creating my "studio" cost nothing other than the equipment and the time to set it up and break it down. It actually helped me learn what I need, as well as learn how to take control of what is in the frame of the camera and what is not.
Good luck! Hope this helps!
