I have a website that is being hosted and supported by a company that is going out of business. We are looking for a company to do maintenance on the code/content side, and will likely move the hosting to Rackspace.com (or another SAS70 certified provider).

We are bringing the CMS with us, which I know is unusual, but we like it and would like to keep it. What companies should I look at for just CODE and CONTENT maintenance? It's a PHP/MySQL website.
