High ticket fitness coach needs social media ad help.

To give you a quick overview, I am the owner of a new online fitness business. We sell high ticket online fitness coaching programmes to clients. I have only been doing organic messaging and marketing for the last 3 months which is where my sales have all came from. I have recently found a coach who can take on clients on my behalf so I am ready now to invest into paid advertising via facebook to get sales calls in with good quality leads. I had a mentor who recommended my ad campaign to look like this. Conversion ad > manychat > message to landing page > followup messaging manually on fb messenger to get onto sales call. I did £1000 ad spend a couple of months ago which resulted in one £1800 client. I have since turned off this ad account (its now disabled and im not sure why), I have since opened a new one. The quality of my leads were not great in my last ad campaign and it took me several hundred £ to find a half decent ad with £14 cost per 1000 impressions, 2.3% ctr which wasn't bad I thought. I want help to identify a really specific audience who can afford to pay for high ticket training programmes, someone to create a high converting ad and manage for the month so I can grow my business and get a lot of sales calls booked in.
