Images needed only for Joomla template

Hi My normal designer is away on holiday for two weeks. I need this job done quickly. If it's done well then this could lead to more work. I have created a joomla template with some default images. Now I need these images replaced, in a nice style in keeping with the brief of the website. the zip file attached gives full details as well as the images that need changing. please read the [login to view URL] included. I would need to know something of your design before choosing a provider. A low res image or a good description with a few examples would do so I could decide who is best value for money regards Chris
