farm accounts high quality

so ive been analaysing the farm accounts market and i realised there is a lot of competence but almost none of accounts high quality (quality followers,organic followers) the point is i have some questions, and i would like some of you if u want if its posible if you feel like it, to help me with the next questions.
1. Whats the worth of a account of tiktok/instagram/youtube of the ranges of 4/5k followers and 10k to 20k, and for you whats the best point/amount/followers to sell the account and get as much money as posible for the amount worked.
2. how big the business can be, i mean rn i am working in a warehouse and my objective with this is making around 3k/5k a month, is that posible if it is how big can it be, and what i mean with that is if there is enough demand to be able to make 10k/20k a month.
3. how much time it would take to make this 0 to 3k happen?
4. ive been looking thourgh some of u and i realised the best combination is phone+antidetect browser+warmer+sms phone numbers+residential proxies, whats the best services or what mix are u using personally.
5. for numbers and money wise what are the hotspots/forums/marketplaces to sell as much accounts as posible.
