Proxy Business Help | Web Hosting Talk

First of all, I understand that some of the people here are not able to share methods and things that I fully understand, but if you're willing to help, you'll appreciate it.

That's why I've been thinking for some time about setting up a proxy company. I did some readings and bought some eBooks. It's hard for me to search for this information online. Maybe I do not know how to look right. I know my market and know where to sell, but I'm having trouble figuring out how to do it. Here's how I can get started. Please correct me if I am wrong.
Proxy resale? (Kind of confidant)
Create VPS proxy server and own proxies? (Not at all familiar)
IP leasing? (Unsure where to lease them)

Am I on the right path? Are there any ways to start a proxy business?
In case you're wondering where and what types of proxies I'm looking for, I'm looking for dedicated proxies for the data center. These proxies are then used by customers on Shopify websites to buy items like Funko or limited edition posters.

If someone is here who has some tips or links, or where I can find or read more information, or if you are even a provider and willing to help me. It is very much appreciated. Thank you for taking the time to read this.
