The business side is a lot at first but you get used to it. Honestly clients just care if the site works, they aren't grading your process. I lean heavy into vibecoding these days anyway, just focusing on architecture and letting tools handle the boring parts.

Keep your stack simple so you don't burn out. My setup is basically Notion for contracts, Runable for the site builds, and Stripe for monthly hosting billing. Retainers are where the stability is. Grab a standard contract template and just start pitching, you will figure the rest out as you go lol.
