Create a introductory business email

I am launching a new business this year and I need to create a business email template introducing myself, the business and what it can offer.

I should be able to do this myself, but due to my dyslexia and autism, this is a minefield for me, and I need to ensure what I send out sells not only myself but my business and will generate leads and bookings.

Please note: I will only consider interest from applicants within the UK!!
