Professional product designer needed for designing a new and modern glass protein shaker.

My business supplies catering equipment. We have decided recently to launch our own new sleek designed shaker bottle. We are looking for a professional designer who is up to this task, has a good experience and strives for perfection in design as this will be one of the main selling points of the shaker bottle, so this needs to be absolutely flawless. It will be a design that exists of 3 pieces. Piece 1: The glass bottle itself with a print on it from our company which is called Mintstack. Probably the name for the bottle will be different, something like freeshake by Mintstack. It needs to have a oval notch in it that is there for a better grip. Ideally the oval shape will be in matt glass. The bottle itself needs to be slim enough to fit in a car holder but wide enough so you can clean it easily. The second piece is the mixer piece that goes within the bottle. Many producers place a shaker ball inside the bottle but I would like to eliminate this as it makes too much noise in a glass bottle, so it needs to be a piece that is stuck inside the glass bottle. I can post pictures for more details. This needs to be in glass too so it needs to fit perfectly in the bottle as otherwise it will break too easily or cause too much noise. The 3rd piece is the cap with an attached lid/spout or nozzle that gets screwed on the bottle. My first idea is to make it out of brushed aluminium but I'm open to discuss other materials if it facilitates the production process. I would like to eliminate plastic as much as possible as it needs to be a environment friendly product and healthy as plastic releases harmful chemicals and makes the drink taste less fresh. It needs to be produced in three color ways. First color way: plain transparent bottle with a blue transparent mixer piece. black print on bottle 2nd color way: Pink transparent glass bottle with black print. transparent white mixer piece. 3rd color way: Black/grey transparent glass bottle with shiny black print, black transparent mixer piece. The bottle should be able to hold 600 ml of fluid inside. The measurement strip on the bottle will indicate until 500 ml.
