Hi, I just registered an Agency company in Travel and immigration Services which would be dealing in Permit processing and travel arrangements. Kindly send me a format of a suitable company profile and introductory letter to potential clients(other companies)

Thanks
Martin

My suggestion is to look at similar websites and look over their company profiles. You'll see a few different "formats". Pick the type you like and do one similar for your own company.

As for introductory letters, search that term here on this site: You'll find that lots of people have asked the same question; you'll see a variety of suggestions.
