Multiple buttons and email auto response function?

I have not yet downloaded this plugin yet, as I am still trying to find a Word Press plugin that I can use with my PayPal account to sell tickets online. I need to be able to do the following:
– Payment goes through my PayPal account
– Show multiple buttons on the same page
– Set the “quantity available” for each button (i.e. there are no more than 10 tickets available for each button)
– The customer can only buy 4 tickets or less
– Display “sold out” when all 10 tickets have been purchased
– Send an email to the purchaser (the email content would be different for each button, displaying specific information based on what they purchased)

Is this something your plugin can do? If so, can you show me the tutorial/steps on how to do so, so I can be sure before downloading and setting up your plugin?

If I were to have any problems with this plugin, how quick in the response time? Because this is for a business, it is very important that the plugin does not fail or can be resolved quickly.

Thank you in advance!
