The only alternative is to upsize your plan. If you are on the basic plan you can upsize to the max plan which will give you 500 MB of total SQL space and allow you to create 5 different databases.
We do not have a VPS plan. We concentrate on, and specialize in, providing the best rock-solid shared Windows hosting available.
If the database size goes more than 500MB, do you allow increase in database quota? and how much would it be?
