No problem at all. RdyToGo has worked with various hosting providers.
So long as your hosting account meets the minimal standards required to satisfy the demands of your website and you grant RdyToGo enough access to do the job we will gladly work with your hosting company. For performance reasons, however, we urge all clients to use a reliable, secure, and upgraded hosting package. We also ask the client to bring all speed and performance related support requests to the hosting company.
RdyToGo also offers hosting services if you are interested in upgrading.
