Proof reading of a 9 page PDF.

We are a small design / advertising studio based in South London (Oval). We are looking to work with a local proofreader on this and other jobs. Most of our work does not need anyone to come into the office but occasionally it will be easier to explain in person that is why we are looking for a proofreader in London. Because we anticipate more work we are also only interested in someone who can do work reasonably regularly - although if this is in the evening that would be fine. The PDF you will need we will send to you but attached is an example. Knowledge of the healthcare industry would be preferred but not essential. A proofreading qualification is essential along with impeccable English.
