Instagram and Facebook Campaign set up and management

I am a new business coach, seeking high quality leads to an evergreen webinar and online course. The online course sales is the ultimate goal.

I need. set up campaigns on Facebook and Instagram that will convert to course sales, either directly through the course landing page or indirectly through the webinar.

I also need ongoing management so that different ads and target audiences can be set up to increase conversions.

Course sells for $625 so I need one to two course sells at least for less than the cost of the course within the first month to maintain the service
