How much does a network install cost?

Excuse me, could you please elaborate on the cost of installing a cryptocurrency network? I understand that there are multiple factors that can influence the price, such as the size of the network, the hardware requirements, and the complexity of the setup. However, I'm curious if there's a general range or estimate that one could expect when planning for such an installation. Additionally, are there any hidden costs or ongoing maintenance fees that should be taken into consideration? Thank you for your time and assistance.
