Build a woocommerce Train ticket/booking system

We need a woocommerce ticket system for train rides.

* Ideally this would be a wordress plugin and work with woocommerce
- will use woocommerce payment gateways
- will support woocommerce coupons

Different ticket types and prices must be supported
- Adult and child different prices etc
- Some tickets will be limited based on max seats on a train.
- Some ticket types will be based on heads, but not seats. i.e. preschoolers and babies
- Some tickets will be discounted if purchased together. i.e. 2 x Adult AND 2 x Child will get a Family discount
- Some tickets are neither head count OR a seat and have their own max sale qty limit. i.e. a Bicycle or wheelchair space.
- Allocation of a person to a specific seat on the train is not required

Export and Reporting of sales is required
- Export as csv file of sales is required for check on and sales at our ticket office. If woocommerce 'products' are used existing tools can be used.

See detailed spec attached.

Suggest;
Milestone 1: would be to negotiate and finalsise spec before continuing or commencing any coding
Milestone 2: Coding and development
Milestone 3: Testing and Acceptance
