Travelling to UK through travel agent?

I have never booked a trip through a travel agent, but am thinking about a trip to the UK. Dont know from where to start the search. can anybody help and tell me the shortcut? i will be there in UK for around 15 days..

Are you talking about booking a flight or deciding where to go or stay? Not sure how to help...

There are so many travel related sites that to try and direct someone to any one place is near impossible so research on the internet is your best plan. you can try http://www.e-zbook.net they have many different companies their at one site to research.
