Hovgaard Games already have the Startup Company game, which i first played before Big Ambitions. And it was quite good.
Since the components and logic are already with the same company, it will be great to include all the website type in the game.
And it should be the same way Web Development company, but instead of working for someone else, the employees will work on their own website. And the traffic can be used for marketing.
This is my initial thoughts, reply more if you have any more suggestions for this.
