I have a VGA going to a monitor that is about 30 feet away. Will that work?

It depends.
In theory the video signal lines are 'transmission lines' theoretically these have no loss or degradation of the signal over distance.
However, in practice you can not match this theoretical performance.
So, the better the cable the further you can send the signal with the same amout of loss.
Also,the higher the resolution and refresh rate the more apparent any signal degradation gets. If you have say 5 nS spread of a signal then at 640 by 480 at 60 Hz a single pixel is way wider than 5 nS and you will not see anything. But 1280 by 1024 at 75 Hz a pixel is 7.5 nS wide and a 5 nS spread is going to be very noticeable.
30 ft is possible, but chose your cable carefully.

VGA has a limit of about 30ft to be able to support 1024x768 without a loss in quality. Any longer and you will probably have to use 800x600 resolution to retain quality.
But I am sure there are some technological advances that allow for longer cables now.

the reason long cables are not made is by using the fact they don't artwork. for that form of distance you prefer a KVM (keyboard,Video,Mouse) adaptor that converts analog VGA to digital video and the full digital documents despatched via Cat5 community cable. on the different end is yet another container that converts it returned to individual factors returned.

I have used as long as 150' with no problem
Just try not to route it close to power wires, as you may get interference "noise" from them,

It should
