Perhaps you would do well to purchase a Zoom R24 first to work on your skills.
I like this one. Besides, it can be a control surface anyway when you do want to step up to a computer program.
Besides that, I will just sound like a parrot here: That's a hefty bill to pay for a studio, but when you add up all the hardwear to do a
good recording instead of just a demo, plus the fact that all you need to do is setup and play - it probably is cheaper for good result to practice your chops tight enough that you can get in and out of there for most of it in a couple of days anyway. Extra time might be needed for vocal tracks or layered extra guitar twiddly bits but; Compare that price, and the result, to the cost of 16+ microphones (minimum $100 each for just the Studio-Mallet 57s), really nice amps, monitors, a huge board, a well constructed room, and so on - and you get a pretty good deal.
If a mediocre 'demo' quality is all you want, which works fine for some kinds of music), it is nice to have a home setup and for that: that Zoom thingy - or a comparable piece, plus a computer DAW (I think its bundled with one if you get one new anyway), amp simulators etc, and a few extra mics will do you okay for the cost of a couple days in the studio. It's gonna take a while to get your technique down though, and still wont be the quality of a good studio 'room' with top-of-the-line mics on nice amps and an experienced engineer.
I know a few but a key would be great.
