I think you know the answer. If you build it, they will come. You could be the Game Master. I was, no one else wanted to do it. I built what I am from nothing but the whispered rumors of a friend. Generally regarded as an amazing game master. I wasn't always like this though. I started just reading the core rules to the best of my ability, and not sweating the mistakes too much at first until I got more comfortable playing. I never knew about my hobby shops at the time, so I carved out my gaming group through persistence. It started small, but quickly grew to be enormous. Then over time almost died off since the older players had real life stuff to do. Now it's stable again. Growing too fast even, too much players can be a bad thing.
Everything I've done has been under my own sheer willpower and determination because I knew how fun it would be. It is worth it because its not an experience someone can just get these days. Was it worth all of the work and cost? Yes, TT RPG's have become a good passion of mine. All I had to go off of was "hey this sounds fun". I bought the books and did all the work and for the most part still do today. Though my players will occasionally chip in. Then again I have come to like collecting these books and reading them just because its so interesting. I doubt anyone will go as far as I have, but still. I was almost broke back then too and saved and scrounged.
I still have those original three used books I bought. Amongst my most cherished ones. I still run games with them 10 years later. Though less often these days. And even back in their heyday of use I played with them for 3.5 years. It's much less expensive when you look at it from that kind of perspective. The books will never be out of date. You could pull them out two decades later and run a game with them again.
Edit
You can even play on Skype if need be.
When your broke and a video game comes out you want you can't get you sit there like a bump on a log. When you have a TT RPG and a game comes out you can't afford you don't really care, since you can play something new anytime you want.
Edit
More TT RPG's then you can ever imagine. http://rpg.drivethrustuff.com/
