I'm not sure about Webhost4life, but they might allow you to connect to a SQL Server DB remotely.
Visual Studio does have some capability to manage a DB, but the best tool is going to be SQL Server Management Studio.
There's a free express version of Management Studio you can download and install.
Microsoft® SQL Server® 2008 Management Studio Express
You'll probably first want to find out if you can connect remotely to your Webhost4life DB. If you can connect to it from Visual Studio, then that means remote connections are possible.
Once installed, you can connect to the SQL server at Webhost4life, open up a Query window and execute the setup script.
