Sell ballots Sweepstakes

[PrestashopTrackglobe]

At the store I am creating, I would like to sell "papers" to a draw held every x days or months per month.

The IDEA could be one of the 2:

1 - Buy the ticket at 3 € (for example), which, using 1 € to cover the cost of the prize, and the other 2 to the charity that I want (dinerod asoaciaciones Estina for protective or animals). In this case, I would have to pay VAT on this "papeletea?

2 .- Buy the ballot to 3 € (for example) and ALL is beneficial. Do I have to put VAT on "ballots"in this case?

But if there is a problem in 2 ways, is like him, that when a person buys a ticket (or more) you generate a "Code" Example: RE-00001 and beyond. So that would make at random a number between those, and who had the winning ticket would get the prize. If I understand correctly, with this, also achieved considerable publicity.

Anybody could help me with this?

Sure it's very easy but I can not think how.

Thank you very much
