Change my existing packaging colour, text and size 15 times - simple task for a professional

I am looking for some to replicate this package 15 times on 15 similar sized packages by just changing the colour on each package where it is blue and green & the text which i will provide. I will provide the colours needed. The image on the top front of the package you need to find and change it. I can provide ideas. Simple and straight forward task by replicating and changing colours and images not design. I have these files ai & psd. You must be able to create colours that look professional and are exactly the same theme and style of this package
