Service / Products

Hi, i am looking for a WP Theme / Plugin that will allow users to purchase outdoor activities.

It is almost like a standard shopping cart, however the admin needs to be able to control how many slots are available for each activity each day (date), and then when one slot is purchased, their should be one slot less available for that activity for that day (similar to a standard shopping cart but stock quantity needs to be managed for each activity for each day day).

If i compared it to a standard shopping cart, for a site that just sells fruit… imagine that it has the following products (which would be similar to activities on my site)
– oranges – apples – bananas

Now imagine that only a certain amount of oranges, apples, bananas are available to purchase on any given day, and that the admin is able to set the quantity available for each date…

Has anyone seen anything like this, thanks in advance…
