ASP.net MVC Web Host for growth

Need to find a web host for our ASP.net MVC website (Hooked to an SQ开发者_开发技巧L Database). To start with the traffic will be quite low but the room for growth could be huge so we need a web host that can dynamically grow if needed to take the traffic influx.

Does anyone have any advice or know of any host solutions for this scenario?

Thanks in advance
