Google Ads / advertising coach

I have a subscription based SASS platform that just launched, and I'm ready to get the word out. I am new to marketing and am seeking some guidance along the process. What this would look like is having a meeting or two to get familiarized with the brand, then provide some proposals and advice. After that we could have ongoing weekly check-ins. I could use some technical help as well, but I am okay to do most of the leg work. I am mainly seeking guidance and coaching since marketing is a new area for me. I have a general idea that I would like to use YouTube commercials to reach people, but am open to more ideas as well. I am also interested in seeing my site be recommended through ChatGPT / AI services, so please mention any experience with this too. Thanks in advance! John
