Add separate products to package - then chose quantity.

Hi,

I need a feature that allows me to place all my 60 separate products on a category page.
It could be.

Screw A, Screw B, Screw C
Hammer A, Hammer B
Machine A, Machine B, Machine C, Machine D

etc.

I want my customer to pick their own little package. And then choose quantity of packages.

Say that customer number one: adds 1 x Screw A and 3 x Machine C in a package.
He gets his price. And then in the next step he decides the number of packages he want.

We are working with gifts, so it's common that companies "designs" their own little packages
and then send it to their customers and employees.
Thats why i need this.

Any help or guide in the right direction will be appreciated.

Kind regards.
