Additional Features? Is this possible? Customized product list

I’m also trying to figure out if I can have the feature of providing shipping quotes by zip codes or not. Can I do this with on of your plugins?

Also on this product: http://sisyphus-cards.com.c1.previewmysite.com/store/products/card-specials/ we want to be able let the client have another option of picking what cards they want for their package of 3 cards and 5 cards from the cards I have above. Can we do this with your shopping cart? OR would this be custom work? If so, cost and can you do it? OR do you know of someone that can? *** Having a check box or something with all product names so client can pick and choose what cards they want…

Please help with this ASAP.

Thank you,

Julie Johnson
