Crypto Node Turn-key Platforms

I run a number of nodes in various forms: solely as NFTs, as participants in the cypto network, as well a s number of DePINs.

The business and economic model is pretty easy to understand from what is available and what I can infer/ derive. Some look like legitimate projects (Timpi & Neoxa ), others, well I think we all know have proven to be a bit more dubious (cough MatchX).

So I'd like to learn more about the technical underpinnings of these networks and understand the barriers to entry,

So lets say I want to start a business with a non-fraudulent real world purpose. A flower shops. I've a great idea to somehow merge crypto and floral delivery underpinned by my new crypto Flower Coin. I will register my business and pay all taxes, including taxes on proceeds from node sales.

So I want to start a crypto node project where nodes are sold, funds are received, put to use, and proceeds from my flower business are used to repurchase my Flower Coin from the open market.

Are there any platforms that provide the technology as a full service?

Or do I have to build all the bits myself?
