Denim Revived

I am organising a website for my mother's small boutique craft business for her birthday on 31 August 2012. She currently sells her products at the local markets and I want her to have an online presence so people can continue to buy from her. I have registered the domain name "denimrevived.com" and have organised hosting. I would like to use WordPress because I know how to use that (I use it for my website) & therefore it will make it a lot easier for me to show her how to update her products, etc, and in that regard, it needs to be a very simple website. Whilst she doesn't need an online store as such to be able to take payments, I would like the website to have the ability for a purchaser to click on the product to "order" it - possibly then an email be sent to them confirming their order with her bank account details with the total purchase price (to add a flat shipping rate for that particular product) advising that once payment is received the order will be shipped. The types of products she sells are one-offs and some of the categories are wine coolers, quilts, pillows, notebooks, etc. There are more and we would like the ability to add any header categories as we need. Then there are numerous one-off products in each category (ie she may have 10 different wine coolers she's made for sale). The idea is that when she makes another product, she will take a photo of it and upload it to the relevant category (ie wine cooler, quilts, etc) and then give it a code so people can order it. Then, once it is sold, it needs to be removed from the website - could this be automated? Please contact me if you require any further information.
