Welcome to the community. There is a lot of helpful information on this forum already regarding the basics, so be sure to read a lot of the threads or search for issues you are unclear about. You can build a small system very cheaply if you have access to some kind of tanks or barrels and put the system together yourself, so you may not need help with initial costs.
