Well, I'm wondering if anything already exists or is easily modifiable to fit my needs. My client wants to be able to rent his vacation home out over the web. He wants a calender on the site with the ability for customers to schedule the days/weeks they want to rent the house. Along with all of this, he wants the customers to be able to pay through paypal on the site as well. (I already told him this most likely isn't possible, but figured I'd ask it here). Would it be smart of me to convince him to just let me setup a custom contact form with areas for the customer to state when they would like to rent the house? Then I could tell him how to update the Calendar plugin to show the dates the house is already booked. I'm not getting paid much for this job, so I'm not spending hours upon hours coding a custom plugin for this. I guess I'm just wondering what the more experienced WordPress users would do if they were in my position. Any and all feedback will be greatly appreciated.
