Website hosting

I just bought my domain name…. This is getting real. And, I am coming to training in August. I’d love to begin to work on my website. But knowing that you will be providing far more guidance in August is that a silly use of my time? I am so new to this I don’t even know if I sign up for a web service, can I just transfer all that I create to whatever platform you all include once my training is complete? Or would it be smarter to begin a closed Facebook group for potential clients? Thanks!
