448349 Budget Hotels Portal

I want to start a budget hotel portal. where hotel owners can sign up as publish their hotel / rates / rooms availability / photos and facilities / payment method. They can login and manage their own hotel through the portal. web 2.0 style. If you have a better idea or a system ready for this sort of business, please pm me and let me know how it works. Priority given to those who can come up with a good business proposal + the website system for this. I don't need a complicated one. Very simple one will do.
