hey looks like you are seeking a professional media buyer to help you to generate high quality leads to your business, one the best ways to do that is by creating educational content as you mentioned plus free lead magnets that are really valuable for them(they will pay for the same information else where and you are giving it to them for free), once you have that lead magnet(you will know this after multiple tests) you will be able to have their contact details and then you can call them to sell them what you want and as well do a re targeting campaign for them with better deals and offers if they haven't bought plus including them into your SEO which will show them how good you are at your craft.
