JEvents for health retreats?

Hi,

Can you please let me know if JEvents (with the Gold sub) will do the following?

I want to make a booking system for a health retreats service (which is basically just an event). Each retreat is for a number of days (let's use 4 days in this example) and is only available for a set number of people, let's say 20.

So I'd like a calendar on the page, showing each 4 day retreat and (for example) it would show that 12 out of the 20 have already been booked for that retreat. Then the next retreat maybe still has 20 spaces available etc.
If there are spaces in a particular retreat, the person can book their slot and pay a deposit (I think just via Paypal will do). They would get a confirmation email, the site admin would get their details in an email and JEvents would update for that retreat now 13 out of 20 have booked.

Once a particular retreat is fully booked, it will show it's fully booked and not available.

That's the core system we want.

And to make it easier for the admin, could I also setup a 4 day retreat to repeat? EG. I want it to show retreats starting every Monday to Thursday for the next year. So I wouldn't have to manually create each 4 day retreat for the year.
