Can someone please help me do this. Or just give me something to write about

Let's do it together here (at least with generic information that won't give away your identity), so that others might gain from our work.

Tell me if you are writing the letter for a specific job. Also, you will want to include in the letter several things about you that an employer will want to know, such as your customer service background or your knowledge in a particular area.

One more question: Will this letter be in place of a resume, mostly an informational or "sales" letter about you?
