Software development and finishing website

Our luxury hotel platform will be a mediator who will offer some of the hotel's facilities to accept or send a counteroffer to the traveler who bid their own price on Hotel accommodation.
However, those tasks need to be completed on the website. Plus while u doing that we need to implement a space to "bid your own price" on each hotel profile. It's not going to work for all hotels but will exist on the hotel profile. The hotel will have a choice to work with bid yr own price function or not. We as admin have control over whether to disable or enable this function.
We will be offering advertising spaces for Hotels, property developers, car hire, and airlines. We will charge around 1000 per year and these profiles will have contact details of the business and link to their website in case travelers would want to book.
