Marketing Advice

I currently have a 35% conversion rate on my offer. I do medical weight loss. My offer is a medical consultation with myself (physician) and one of my Registered Dietitians. Listening to Brooke’s teaching, that seems like a good conversion rate so now I’m thinking I should market better. I’m looking for advice on what you think is best – pay a marketing company, learn my own Facebook marketing, do a podcast, other? I’ll go through SCS and see if there is additional teaching on marketing strategies.
