Think this would be the right place to post..

Been thinking about moving house for a while now and was hoping to put my own home on the market early next year. My girlfriend has a friend who is very interested in buying my house (almost immediately) and I do have a house in mind to buy which is already on the market.
My question is will I need to involve an estate agent or will I just need solicitors? what do estate agents actually do, apart from advertise your home?

All help appreciated
