Need help building my first barndo!

Hey guys! I'm a 20 year old male who owns 50 acres in basically the middle of no where but I'm looking to build me a barndominium house on it. I've looked at a few videos on how to get started but it all sounds the same to me and I can't decipher what needs to be done and when, basically the order of operations of the entire build. I already know I will need to install a septic system and a sistern/well on the property since I'm basically in the boonies.

Relevant info (I think?)

I have $27,000 saved up to help with down payment however I don't want to use it all as I need an emergency fund

Credit score is 759 although I've never taken out a loan for anything (I paid for my car in cash)

I make $23.90 an hour currently with varying amounts of overtime (ranging from 46 hours to 57.5 hours)

Also I'm going to be needing a general contractor to help me with hiring help to complete the job as my father and I can only do so much together when it comes to trenching etc.

Any insight and/or help would be greatly appreciated!
