Photoshopping Product images

I work for a nutrition brand and we make supplement kits. We always use bright fun boxes/backgrounds when shooting our items. I need help photoshopping our entire range as we took the pictures in house and they're not the best brightness/saturation etc. Please look at our Instagram gp_nutrition for a sense of how we use colors. Also some of them have fruit/veg so we'd either need the vegetables and fruit photoshopped in to look bright or you to bring out the color as much as possible.

We need help photoshopping our images to be used in marketing assets. ASAP
