Magento custom attribute to show up next to product price

Hi there, I have a website that I'm currently building with Magento and a custom theme from themeforest called Ultimo. The website is [login to view URL] Some products I sell are sold by the square metre (m2), some products are sold by the piece (each). I have setup a new attribute (tiles - Sold_by) so I can insert this information for each product. I would then like this attribute to show up after the price on the category pages and product pages. At the moment the attribute shows up if the product has a normal price and a special price, but I need it to show up also if the product only has a normal price. If possible I would also like this to show up on any other pages where the price is shown - so the checkout page etc. It's probably best to contact me if you need more information. Thanks Ben
