Direct mail

[Adam Amero]

Hey everyone, I'm getting ready to send out my first direct mail. I have a list of 20 vacant property owners I'd like to mail. Im planning to send out actual letters, me and my brother have bad handwriting so we're trying to type up the letters. As of now I think it looks kind of stupid, it's going to be a full sheet of paper with only a few lines telling them we're interested in buying their property and our contact information. 

Does anyone have any advice on setting out direct mails like this without using a company? Any advice or suggestions are appreciated
