Letter format for Campus Placements

Hi Team,
Can anyone help me with letter format to be sent to Colleges stating that we would like to visit their college for campus placements.

First and foremost is a gist of presentation on your organisation, which makes more impressive to attract the present generation of young college students with tech savvy, freedom of loving. You should also keep in mind such conditions as reflecting, a negative culture of the organisation with gen-Y work force so active on social media 'face book' and 'whats apps'
