booking reservation event

I'm searching for a product reservaton/booking system for my members. I need a reservation/booking system where the members also can do reservation and booking business with other members like conference rooms, meeting rooms, tools, jobs etc.

The most important is the possibilitie to let members rent/sell their own products and show their availability to other members and let the customers (members) be able to hire the product.

Muy buenas, me dispongo a realizar un proyecto web para una empresa de eventos.
La web principal sería una web de presentación de la empresa.
Dicha web tendría venta de artículos y una serie de subwebs, una para cada evento. Mis dudas son las siguientes:

Punto 1 - Teniendo en cuenta que cada evento tiene su propio dominio, su galería, patrocinadores, noticias, inscripciones con pago electrónico, etc... Pensáis que es mejor hacer webs independientes para cada evento o crear un "megatipo de contenido" para crear eventos desde la web principal?

Hi guys,

I'm new to drupal and not sure if this medium is a forum , module suggestion or both but I can use the help of some experts on booking systems in drupal.

I have searched the internet for a particular drupal module but I have not found a suitable one.

I need a module that would aid a particular booking/reservation assignment with the following characteristics.

1. It can be modified so that the calendar day view will show each hour in quater, third or half hourly divisions rather than one single hour
