Order Delivery Date

Hello,
I am making online store for food catering company and I need some help 🙂 The function I am looking for is that for example there will be Eggs and there will be Cake. Eggs will be avaible immidiately but Cake in for example in two days. I need to show to customer that because the Cake will be made in two days, the whole delivery (even the Eggs) will be postponed to time when will be cake avaible, so whole order will be postponed by two days (always according to product which require longest time to prepare). Do you know such a plugin please? Another function I am looking for is shipping based on Kilometres between customer and shop. Thanks a lot!
