I need a photographer for my vacation in London

I and my 7 years daughter will be in London between 10-18 December. I would like to have a freelance photographer, who will shoot our photos in a few locations during 2-3 days. I want 10 to 25 photos. We can divide the time into two or three days, like 20 minutes for 3 days or 15 minutes for 4 days, or 30 for 2. We can schedule it together.We don't need so much professionalism but rather a friendly, natural and relax style shooting. I could do it myself but I don't want to carry my huge and bulky camera with a kid. I'm flexible in terms of locations and time, but no too much flexible in terms of our budget as pound is fivefold of our money:)
