518717 Contractors website

Need a website where I can network with other contractors. I would like for each contractor to be able to login and keep records of all their vehicles along with all maintenance for the vehicle, parts and part numbers. I would like to have all my employees information within the login page. I would like to have a contact area that has all my business contacts. Vacation calendar so I can post all my employee scheduled vaction on it. I would like a chat area for all the contractors to chat. More details will be discussed.
