Ticketing system in Laravel

Custom 'raffle' system needs setting up on wordpress site including all the below. (Artwork will be provided ).
Ability for a number of competitions running at the same time, all editable by us to add relevant questions / change the number of entries etc.
Main page showing all competitions. Single page for each competition.
Users must answer a question to be able to enter the draw.
We would like to use Stripe as the Payment system, this will need setting up to allow the site to take payments by credit/debit card.
Raffle numbers will be selected at random from the available numbers, once purchased these will be emailed to the buyer.
Once all tickets are sold (we need ability to set the number) we will pick a winner.
