Q: How many searches did you make before posting this question? A: none
At the very least, take a guess at the solution, then we can help move forward from what you know already.

Wrong. I searched your entire post. Nowhere did you mention a price or provide a (clickable) link to where more information could be had.

Sorry PaulS... Pricing wasn't mentioned, but freely available upon enquiry, because different people will want different variations of the bundle.
You can see pricing for the complete product with software on eBay, or enquire for what you need.
