Design a Logo

Hey, This is a label design work-post for a start-up supplement company, aimed at gym-goers, the bodybuilding market, and general health and fitness. This particular label will be used to sell Whey Protein tubs. The dimensions of the label are as follows; 306mm x 155mm (1kg Tub) 450mm x 130mm (2-2.5kg tub) The design will need to create a text box to the left and to the right of the central image, for disclaimers and other information, as well as the nutritional label. For this, i ask that it could be produced in a way that i can edit it after it's produced. This is so i can write all the information in there and play with the font! The brand is called GenoFit, and the product Whey _ _. Where _ _ is will be either "90" or "80", this should be left blank so i can add either one depending on which product ill have in the tub - so this is a generic label. Id like a logo for GenoFit at the centre top, in a very clear and eye-catching way, with Whey underneath. Perpaps genoFit at 30 degree angle or something and then Whey straight as normal underneath. I'd like the label on a whole to be a dark metal/gunmetal grey colour, verging on black, with all fonts being white and GenoFit being a nice happy green. It can't be khaki or fluorescent green however, it needs to be flat yet visual and bright.
