Photoshop editing

I have some product photographs which I would like to have edited and brought up to a professional standard, ready for website representation.
To get an idea of how the the products should look, please take a look at some of the images on www.togetherhealth.co.uk
My products are of similar style packaging and as such, I would like the end products to be of a similar or better standard.
I would want to see a free example of what you can do with my images before assigning the entire job.
