I am currently working on a project where by a customer should be able to pick a computer from the store to purchase and be presented with a list of components to add (just like a configurable or bundle product) however I want there to be a limit to how many components they choose.
So for example user picks Computer #1 and should only be able to choose a maximum of 10 components to add to the machine even though there is a list of say 20 items.
Once the user has selected say 3 hard drives, 2 monitors, 1 keyboard, 1 mouse, 2 gfx cards, 1 sound card then they would not be able to choose any more items from the list.
I think this needs its own custom product type. If someone can do this please bid on the project. If you have no previous experience with Magento please do not bid.
