Firstly, I'm somewhat concerned about the fact that you're offering what seems to be a service without any mention of a scale of charges - are you doing this for nothing?
If you are, then you should say so. If you're going to charge for your service you need to make some changes. Firstly you'll need to state upfront what qualifications you have, if any, and make it clear that you're not offering legal advice. There are pitfalls involved with doing that unless you're a qualified lawyer.
If you're charging you must, by law, include a postal addres and telephone number where you can be contacted during normal working hours. It's also necessary to tell people that you are UK-based, and that you can only offer advice/help to people who live here. It's easy to forget that your site will be visible all over the world, and you don't want to be involved with people in other countries.
Helping people with consumer complaints is a complex and often frustrating experience, and you'll need to be aware that people will come to you with high expectations - it's all very well being tenacious when resolving problems for yourself and friends, but it's an entirely different thing when you're doing it for many people at the same time, especially when you can see straight away that some of the complaints aren't justified - people don't like to be told that, as I know only too well, after six years of doing it.
On a practical level, your site needs images, and the layout requires revision. People buy with their eyes, and unless you capture their attention within ten seconds of their arrival on your homepage you'll lose them. Your text contains numerous errors, but that can easily be solved with some careful editing - 'freinds' should be 'friends' for example.
