I found that one of the most effective ways of getting more B2B client projects is to build great relationships with a few other businesses is to start by helping them for free, and proving your value. Soon enough, if you're really good at what you do, they'll be asking you to help them with a lot more things, which you can charge for. Make sure that you are being genuine and truly want to build a relationship with them and work with them. So you should handpick the entrepreneurs or businesses that you admire and would like to work with.
