Wordpress-Plugin / PHP Expert

I'm looking for a wordpress-plugin professional who could extend the wordpress-plugin : booking-calendar (hotel edition) => [login to view URL] I need that you EXTEND the plugin. !! You don't have to change any of the plugin files.!! The Plugins have a lot of hooks and filters to build the required functions with external scripts (small additional plugins) What i need : 1. I need the possibility to setup a minimum amount of days for renting a resource at the resource-edit-panel for each resource. Currently it's only possible to setup a minimum amount for all resources. e.g. If i setup a minimum range of 5 days the resource could not booked for 1, 2, 3, 4 days. Only for 5 days or more. 2. I need the possibility to setup a blocking time after a resources was rented, also for each resource. In this blocked time the resource could not booked again. e.g. If i setup e blocking-time of 2 days. If a resource was rented from 2011-09-01 till 2011-09-05 the the available date will be 2001-09-08, because 2 days are blocked. 3. I need the possibility the accept bookings at the backend and mark the time as 'reserved'. After a customer booked he will get a mail that the booking will be checked. The time-frame will be marked as 'reserved' and can't be booked from an other customer. If the admin accepts the booking the customer gets a confirmation mail and the time-frame is marked as booked. If not, the customer will get a denied message and the timeframe will be freeed. 4. I need the possibility to store the credit-card information of the customers and do the credit-card payment after the admin accepts the booking (see point 3) As described this features should be implemented by generating a plugin that extends the functions of the booking-calendar-plugin. If there are some hooks or filters missing, the programmer of the booking-calendar-plugins must be informed an he will extend the plugin with a new hook/filter. You have to work on my demo-server only and will get access to a folder to store your plugin-files. You don't get file access to the booking-calendar-plugin. Payment : Each requirement will resprent a milestone. We will ad an additional milestone for bugfixing. I will upload the esrow-milestone payment before a milestone starts. I will release ALL payments after the full project is finished. If you can't deliver the required functions or you can't deliver in time the project will be canceld withou ANY payment, even there are things done. With your bid you agree to this terms.
