Free products - "call for price" and payment methods ?

[dmb]

Joomla 3, VM 3.0.10

I can't see how to even approach this problem, so I'd love to hear if anyone has ideas.

One of our products is an Annual Membership. This is priced at £15.
I have a child product which is Student Membership that is free for a year. This has an override of £0. When this is selected the "Call for price" button is displayed. I've changed the language setting so that the text "Free !!" is shown instead.

I have two problems:

1. Clicking on the Call for Price button causes a little 1-line blank popup to appear. Clicking on the button again get rid of this. What is it ? How can I change (or remove it) ?
2. If the zero-priced product is added to the basket, checking out still leads to Paypal with a zero balance which is not valid (Paypal will only display "Please enter an amount greater than zero."). What's a good way to have the order created so that the shop admin can approve it, without forcing the shopper to go through payment ?

Even better - could I have a different payment process for this zero-priced product (e.g. upload proof of being a student) ?

Thanks for any help !

set a minimum ammount on the paypal plugin

set up also a std. payment method -- blank except for max amount 0.01 - call it Free or something
