Do some 3D Modelling

I need to have a jug for a product designed and drawn in 3D digital to supply to a packaging company, The jug has to contain 5 pounds of raw material, as in a traditional plastic Whey protein jug, but it must have two compartments in that it will contain 2 separate products in one package. Essentially a large container that has a lid that twists on but split down the centre to allow two different supplements to be housed inside of it. The container needs to be user friendly in that it will be accessible from the top but have enough room to fit your hand inside of it to allow you to scoop out the dry crystalline substance. Usually, the jug that contains whey protein, is tapered at the top giving narrowing at the mouth so this would have to be adapted.
