I've closed many clients now for sites and the biggest thing I've personally learned is to finish the first project and immediately think of other ways to add value. I came up with this content blog posting system that finds relevant content (This one finds Reddit and Quora threads in the specific industry) and then it will post the content on LinkedIn or wherever you feel your most qualified leads are located. I gave this exact model to an agency for $1840 a month and they signed for 6 months with me. My job is to maintain it, make changes as necessary and keep them updated/informed for any optimization. Good luck everyone and let me know if you have any questions!
