Donna,
There are many great hosting companies out there and i would suggest you check out threads from others about who they are using. Wordpress.org is one of the best applications to create a dynamic site and once you get going there are many talented VA's here who can customize for you. The best part is it is great from an
SEO standpoint and easy to change and update from anywhere.
My only suggestion is to stay away from free sites and web builders as they will only become cumbersome and not easy to grow with you when the time comes.
