Hi,
I've written sales emails for small companies ranging all the way up to Edible Arrangements, a billion dollar company.
You didn't provide much information regarding what the email would be selling, but I'm confident in my ability to sell just about anything. English is my native (and only) language, and at a time it was my major at Boston College.
If you're in a rush I can get the email done for you within a day.
Thanks for your time in reading my proposal and I look forward to hopefully talking to you soon!
Cheers,
Rish
