No, you don't need help. You need to help yourself. Do you expect people to start listing providers based all over the UK? Do one.
Use the search function to search for mmf. Identify profiles of interest to you. If you need further information, check reviews. If needs be, ask a question in the relevant region, but be specific. And post a link to the provider you are asking about.
What you pay will be completely dependent on the options, and also where in the UK you are based. If it's going to be too expensive for you, find a cheaper option or don't book. You can easily find out the going rate for 2hrs by doing your own research - check AW profiles in your region. No chance I would pay a lad to shag a bird with me, but it's up to you. Best way of going about this is finding a mate, and booking 1 girl between you. Normally, she will charge you both the hourly rate. So she earns double, but it's no more expensive for each of you than if you'd seen the girl by yourself.
