Welcome to the LF world and the LFP community. The pool of knowledge, experience and talent here is deep and wide.
Jump-In? Two ways to go there. Either go all-in with a brand new high-end outfit (Canham, Linhoff, CVhamonix, Schneider, etc.) and that will be in the thousands . . .or slide in with a kit of used and/or ower end components (Speed Graphic, Burk & James, Ansco, Kodak 2D and so on).
Either way, there will be a learning curve in technique (EVERYTHING is manual) and a significant adjustment in creative process. However much you think you want to create images in the style or spirit of an established LF photographer, in the end you may not enjoy the continual direct manipulation of the gear (I do) or managing all the moving parts of a LF outfit. I have, myself, forgotten some small, essential and expensive piece of gear and walked off irretrievably leaving it in the tall grass. That's a hard lesson to learn.
Whatever you do, please post here and let us know what direction you take and how it is going.
Cheers
