ISO of simple yet informative Website Builder for a small business

I'm looking to start a small service oriented business and want to build my own website using a simple website builder. I've used and paid a lot for one in the past for a different company years ago, but this time I'm looking for something I can just do myself relatively inexpensive and easy but that looks great (that I can import videos and pics into), many pages, linking multimedia, email maybe, payment options - though I will not be selling anything from the site, just for payment for service.

I'm new to this, so is there a way to link Quickbooks? I'm still using an old version that I manually just email individual invoices on. Maybe I can do some of this online.

I want something simple, yet informative and easy to use for both me and the client.

I use a MacBook Pro daily.

Any suggestions?
