Joomla help needed ASAP!!!

Hello freelancers, I'm in need of your help. I'm doing a Joomla project with a friend and we're on a tight deadline. We don't have time to figure the problems by ourselves. What I need is: 1- A booking extension (this is a hotel for pets) and we'd like a booking extension so guests can book online just like a normal hotel. I've search but couldn't find something that would meet our needs. It needs to be free (we're not yet getting paid for this, so we have to use what we can get). 2-A live video extension so the client can see his pet's activities (also done by booking a session) 3- Some minor CSS fixes 4- I need to have different users (vets, pet owners, pet carers and registered users). I have one menu that has the options for all of them but I want each to be able to access only the assigned menu. I'm using metamod to control the menus. The website is on localhost, so I'll send you all the files and the database, so you can work with us. Please note: I can't pay more than $40 for this. All I need is some help and guidance. I'd like someone who would help us finish this by the end of the week (next saturday). I'm doing most of the work by researching but it's taking time. I've done a joomla website before, so all the work relies on finding the right extension. Please, give me an idea on how you'll help me and why should I pick you. This is perfect for people trying to start on freelancer since I give great feedback for a great job. If you have any questions, please let me know. Thanks
