Your situation won't stop you from getting into the business. You won't "fail" (seriously, your friends talk to you like that?). Even if your setup is far from ideal you'll get some work, so it's no reason not to try. You can work on things that will allow you to take more bookings once you've got started, it doesn't need to be all sorted at the beginning.
I don't think not driving is a big problem, anyway. I don't drive, and I'm not willing to go to someone's home without security anyway. For local hotels I take a taxi and if I'm going further I use public transport. For home visits my driver always takes me and is outside all the time in case I need him. If I did drive I'd probably still use taxis for local jobs because it's convenient. I'd be able to go to hotels in more places than I do now, but not doing so is not that much of a loss. You're not in the sticks, so there should be a reasonable amount of local work available to you.
When I started I didn't have a driver so I only did hotel visits. That about halved the work I could do. If you're willing to go to homes without security then you can get a cab if they're not far away and that'll make a difference, but it would help to find a driver. If you don't have a suitable friend you could try connecting with local girls once you're on the scene. They may have recommendations.
You can afford a website. Mine costs me almost nothing because I made it myself. If fully designing your own site isn't for you, Moonfruit.com is a popular place to start. You can have a site for free or pay a little to remove ads and use their templates to create a site. Rare-escorts.com is another way of getting a site for free, you get a site based on their template. There are also sites such as adultwork.co.uk and selectanescort.com where you can set up a profile for free and aren't required to link to your own site.
Photos are more difficult to sort out. When I started I used a handful of pictures of myself that I already had and were suitable. You might not be able to do that, especially if you want to hide your face. I've got some really good photos for free by doing time for prints, but that only works if you find a good compatible photographer. A lot of aspiring photographers will be happy to take pictures for free if they can use them in their portfolios, but most of them are probably rubbish and/or pervs. Taking decent pictures yourself is possible, I've got some nice shots that I took with a timer, and some stills that I took after recording myself on webcam. The webcam option would just be something to start with, but you can get one for ?20.
An alternative to having a website is advertising in the local paper (if they allow it). You'd have to describe yourself and your services to every caller which doesn't appeal to me, but there is business there and that way you can be instantly in (and out) of the business.
Another option is working in a parlour. It's quite different from being an escort: you'd do mostly half-hour bookings or less and give half your fee to the house, but all the advertising would be taken care of and you'd only need to go to once place. The price you pay for convenience (apart from the house's cut!) is that you'll need to spend full shifts there and there's no guarantee that you'll get any clients while you're there.
