Dear Sir/Madam,
I would be happy to work for you. Proofreading is my passion and I have been editing and proofreading articles and books since my first year in university, nearly a decade ago. I have plenty of experience and plenty of time as well. The more work you have , the more efficient I will be, since the load of work is my drive to do my best.
I sincerely hope to a good contribution.
Warm Regards,
VM
