I think if you have a model you should not rely on others for traffic, the less people you pay the more you gonna make, lets say worst case you split 50/50 with the girl and you bring in 10k usd, 1k usd total gone to chatter, proxies, onlyfans crm software. If you have someone running traffic for you, minimum you will pay is 10-20%.
From 10k 2-3k goes to this guy who brings traffic, girl gets 5k you get 3-2k and you have a chatter etc cost of 1k you will have 2-1k usd from 10k,
To bring in traffic, you can use reddit,tiktok,ig these are the easiest right now. You will always have a 1k cost for the onlyfans, for traffic on reddit you can 10x whatever you invest easily. For tiktok and ig promotion is mainly free.
I wouldnt suggest you start with dating apps because its hard , but dating apps brings you the best and highest quality paying subscribers, and you can control how many subs you get, more accounts = more subscribers.
