Hello guys, I'm a web developer and want to offer my service to local business owners. I think first thing to do is send an email and after that to call that person. I have searched a lot of potential clients, about 80% of them don't have any website. So what should I point out when sending an email or calling? How I need to introduce myself? I must be more official or friendly? I should send them samples or not? So any tip will be appreciated. If you can propose any material about this topic, it will be awesome. Thanks in advance!
