I am looking for a web designer to update a magento website with the following:

New images
New wording for each product
New prices
Graphically design and change the front page of the website (Just one simple page)

Please can you let me know:

2. How much to add either 40 or 80 images, text, prices and one new front page image
3. Please can you show me examples of previous work
