Less than $200 wont even come close to giving you what you want. One thing you may want to consider is purchasing your own equpment and implementing a system that is ipad controllable - again, the budget is not even close to $200 but would be your cheapest option. But at least the ipad would be more than a remote.

We use Bitwise Controls as a control option for people who want a sophisticated control system without having all the risk and cost of the hardware. However, it is not inexpensive and it is pretty amazing.

There are cheaper versions of ipad control out there with third party equipment, but I think they lack in features and forward mobility.
