Dear Sir or Madam,
I qualified in law - in the UK - many years ago, and then spent 18 years in stockbroking and fund management. I have been engaged in, inter alia, financial and legal documentation - fund and company prospectuses, listing particulars, leases &c. - for most of my working life. I have also prepared listing documents for US companies and worked them up with US attornies.
I believe that I have the skills required to proof-read your document. I look forward to hearing from you.
Yours faithfully,
Edit-or-Proof
