How much cost and time is it to remove paint from the front of a house

We are keen to remove 2 layers of paint from the front exterior of our house. It is a mid terrace edwardian property in London. One part of the job would be safe removal of the paint and the second would be rectifying / repointing the brickwork to bring it back to a good condition. How long would a job like this take and how much would it cost?
