Plugin for custom packages?

Hello, I wondered if anyone can recommend a plugin or solution?

I’m building a website for luxury tours around the UK that the customers can customise online. They need to be able to construct their tour by selecting activities or modules. There will be set routes and experiences, but I want there to be an interactive option for them to customise their package to suit budget, season, timescales and personal interests. In terms of functionality,this will be set up to take payments and bookings online.

I’m just puzzled, does anyone know of a plugin that would give this custom package option/feature or any work around to get this functional?

Many thanks for any input!
Louise.
