Product Photography

I would like product photography done. Images need to be on plain white background. High resolution, pic size needs to be approx 488x488.
We are a Jewellery and Accessories company, the product is for our website and varies from fashion jewellery, to fine jewellery.
We are looking for images to be done as soon as possible, if we are happy with the photographer and the price is reasonable then the business would be on going.

Initial images for now would be 40-50 minimum

Thanks
