Standard cost benefit analysis: does the time spent coding and maintenaning the tool offset by time savings or value improvements? Your pitch is whether you can come in and present a build or buy choice...I think the internal problem space is pretty vast, but if you think you've got something to offer and you can present useful functionality in ten lines of code, you might have a chance. You'll need to get some people raving about how much time and headache saved, I don't think any amount of conventional marketing will convince your target audience.
