Letter offering my services of painting

I want to introduce my company to new clients?

I'm a Freelance IT person doing computer administration, maintenance, purchasing, troubleshooting, networking and others. I want to expand my horizon of clients by introducing it in schools for their IT services. The problem is I don't have a business letter to begin offering those services for...

I need to write a introduction letter from administration to referring md's regarding new start up for mri services in their area.

Hi I have started my own business, but I have problem writing letter to other small and mid size businesses to offer them services and introduction about my company. My idea is to email them first this letter. Can anyone help me ? Thank you
