What you really need is someone who is willing to belay you, and if your really determined, try a little rope solo aid. When I started 50 years ago, there were no books on the subject and I pretty much taught myself, with an occasional partner, who was patient. Within a few years, I was doing routes on El Cap, and elsewhere. It really depends on your motivation. I used to say doing big walls is just a lot of work. At least today, with the use of cams, you will not be attracting a lot of attention, since you won't be pounding pins in, at your local crag.
