Add 301 redirects to htaccess

We need 301's added to our htaccess file and tested to work. We are launching a new design for an online store so the domain name will remain the same but some page URL's have changed. I have a list of the old and new URL's so all we need is for these to be setup and tested to work, ready for the DNS to be pointed to the new servers. You need to be available right now and have done this many times before. VERY easy job for the right person.
