Ok, here is what I'd do if I was you:
1) Buy the book and read it, make sure you understand what you are doing.
2)Create few accounts and see if you can put the theory into practice.
3)Start selling and see if the "I think they'd sell well" theory holds up and if you are actually generating those sorts of numbers.
4)Keep it going and see if you have a long term business model here.
If everything is working without problems and you can handle stealth and sell well, grow.
5)Read about VMware and look into
VPN services 24vc.
6)Repeat steps 1-4 in VM
If everything adds up and you are still running smooth, grow.
7)Create/Buy more accounts and grow your business.
I very much doubt you can go from an idea, to 30 accounts. You need to test your business model and everything that comes with it.
Its all good on paper- I will buy for X and sell for Y and next year I will be buying houses, boats and bitches.
In reality, you need to work around numerous different "problems" of stealth operations and do so without losing accounts, losing money, not paying taxes and so on.
Also markets change- Whats good today might be crap tomorrow, T&C can change, you might get linked with all accounts... literally **** happens.
