add some products to a joomla shopping cart and some minor html changes urgent

Hello I need some products added to a website shopping cart for a company that does packaging products. There is approx 7 categories and within them is approx 3 to 4 products each. Each product has a different sizes and quantities and is currently shown as a drop down box. This is a very straight forward job I simply do not have the time. There is also some very very minor html changes that are no more than a half an hour of time. The website and shopping cart is already totally complete, and already has 1 product category installed. There is no weight to deal any individual postage . I simply need the products installed, variations available and a picture of the product, my client will write the product descriptions. Will require one simple postage change fixed cost of ?8.49 and free for over ?50 One product is a special offer of a mixture of items we have a scanned copy of an A4 page which will need to be added I need this done asap, no beginners, pros only please Thanks Paul
