Upgrade of vm, fix paypal emails, set minimum quantity

[jenkisan]

I have version 2.0.12f with joomla 2.56.  This is what I'm looking for:

1. properly upgraded to the last stable version (2.68?)

2. fix paypal so that is work properly but especially that is sends emails when an order is approved by paypal to both me and to the buyer (some reason this just stopped working one day out of the blue - maybe its the upgrade issue)

3. I used to have a minimum quantity check on the cart.  The total quantity in the cart has to be set to a minimum of 6 units of ANY product.  After I did the first upgrade from 2.0.2 to 2.0.12f this stopped working, so I need it fixed.

Time frame as quickly as possible because my store is down!

If you have any questions, lets me know.

Thanks.
