Letter of response proofread and edit

I require my letter and response to be proof read and edited. The letter has been written and proofread by myself and a friend however I feel it is necessary to be proof read and edited. The details of the letter will be given if I am interested in your services.

What I require is:
- A proof read - spelling, grammar and punctuation
- Edit to make it more professional where necessary
- Any other important factor or explanation you feel will be beneficial to the letter
- UK English - spelling and writing

Avoid editing my appendices titles please. If you are interested please do message me. I do have other work to be proofread too which will be awarded if I am happy with the service.

I look forward to your reply.
