MIS / W2P - how much does it cost to play?

I've been reading that a W2P system isn't as powerful as it could be without a reliable MIS backend - which does make sense.

But where do you start when you have neither?

Even an inexpensive W2P system can cost hundreds of dollars a month which can be a sizable amount of money for a small shop.. Is it worth it?

What are the various monthly (or yearly) price points for:

A decent MIS?
A decent W2P with web design and ready-made templates?
A decent integrated MIS/W2P system?

..for a small, low volume digital shop with 2-3 employees (entry level color press, 44" inkjet & laminator, color plotter, finishing, etc..)

Thanks,
Joe
