The cost estimate for development, launch, and operations varies a lot, but is in the $0.8-$2.0B range. See the cost roll-up on page 163 of the above document. It's ~0.5-1.0 meter telescope, and detector cooling and data rates are an issue.
The scientist quoted in the above article, Amy Mainzer, is leading a more detailed study which is among a handful of proposal concepts (not all NEO-related) that NASA will select from.
