Wordpress site problem needs fixing

There are 2 fixes needed, I simply don't have the time to do them: 1) Wordpress site has been designed by a company that has embedded various woocommerce files into the theme (including single product file), which limits ability to add aditional functionality. I need specifically for the "woocommerce all in one currency converter" to work on these product pages (i.e. to give the visitor option to see the product price in different currencies). So the woocommerce files in the theme are going to need adjusting to work with this plugin - the site has the latest version of woocommerce installed, but the woocomm files in the theme are from version 1.6 NOTE: although the site is using woocommerce, it is not an ecommerce store, it merely shows the price with no "buy" button. 2) There are various forms on the site. All of these forms call an ajax file, which then redirects the submitted form to the previous webdesign companies servers, before forwarding them to the website owner. This ajax file needs modifying to send forms directly to the website owner, so will possibly need some kind of simple php file for handling the form submissions too.
