Having someone build a proper website can be expensive. I would suggest you start with a) the hosted website offered by owner reservations for several reasons such as getting free included support, or b) purchasing a WordPress theme that features a hotel or rental theme from a place like envato or c) consider using Wix or Weebly to build something as a starter.
There is a lot that goes into building a website, and your website builder may not really know what they're doing or may charge you thousands you wind up with nothing better than what I said above. There's a lot to be said for starting simple and then transitioning to something that you have built for yourself later.
