I woul like to send this letter to corporations and genarate my on leads through there employes . The company that I am with doesn’t have a Relocation team. How do I go about this? Thanks for any help you can give me.

Have someone in a professional capacity do the writing for you. If this question is an indication, your writing skills are not sufficient to present an effective presentation.
I would also have a flyer outlining your services drafted to enclose with the letter. Of course enclose your business card.
Research the corporation and look for their relocation department. If they don’t have a relocation department, try human resources and address the chief officer by name.
(But take vienna’s advice and have it done professionally. Your writing really isn’t 100% up to snuff for what would be essentially cold-calling where a good first impression means everything.)
1. Write the letter.
2. Call a professional business writer to help you hammer it into shape. You’ll find these people in ad agencies and public relations firms.
