I've been asked if we can provide a webs service to enable order pricing - returning info to customers in real time. My response was "Of course we can". I've always wanted to build one and now is my chance.

At this point, I think I have a blank canvas. As far as I know, we are setting the rules for this.

So... I'm looking at the IWS server and some examples but could use some guidance.

Input will be:
Company Code
Customer Code
Array of items and qty's (could be 1 to 900 items)

Output will be:
Company Code
Customer Code
Array of items and qty's and prices and ... (tbd) (could be 1 to 900 items)

So....
I'm estimating volume will be a few hundred inquiries per day but could be a few thousand down the road.
Is IWS a good engine for this? If not, what is?
SOAP or REST?
Best practice for handling varying amounts of return data?
XML or JSON?
Any other tips or suggestions?

Thanks in advance.
