We only offer SQL 2008, but you should be able to upload your SQL 2005 database to the SQL 2008 server, as it's backwards compatible. So if you have a SQL 2005 database in your local environment, it should technically work just fine if uploaded to a SQL 2008 server.
Also try reviewing this kb article for steps and instructions on how to move your SQL 2005 database to our SQL 2008 server. http://support.Winhost.com/KB/a699/how-to-migrate-from-your-local-sql-2005-database-to.aspx
