1) Building your website is the first step. The website will tell potential leads everything about you in terms of experience, expertise, completed projects, clients, and much more. This will be the fastest way to monetize your skillset and there are a lot of places (FB, Youtube, Google, etc.) from where you can generate leads quickly if you are good with putting in money.
2) Writing blogs and generating ad revenue is complex. Writing blogs is no longer as lucrative as it used to be. A content shift is happening and video content has already speeded ahead of blogs. So, if you want to go ahead with content, I would recommend focusing on video content rather than blog writing. Podcasts also have great potential nowadays.
