Customize and get a wordpress Booking Plugin to work

Hello. I would like to implement a "Booking" Plugin on my blog which allows the public to enter their contact information AND click on a calendar that will reserve a set amount of time for our services for them. The plugin is VERY simple, its the customization I need help with. The documentation for the plugin is very precise and I am 99% sure it will do what I envision for it, but I can't figure it out exactly. As of right now a visitor can book our services on a particular day, but what we need is the ability to have visitors book us for an entire week, from Sunday to the next Saturday. In the documentation it does say and show how to do "ranges" but I don't have the time to figure it out completely. That being said, I think if the winning freelancer is able, it may not take more than 20 minutes to do, which is why I'm making it a Micro Project.
