I made an App for a company I work at that helps write proposals quickly. My boss thinks it's a good idea to sell so he put me in charge of the marketing. Here's the website http://webproposalgenerator.com.

There's a demo on the front page and stuff. If you think there can be any improvements either to the front end or the app itself, or even marketing tips, I would greatly appreciate it!

Keep in mind that I'm still constantly improving it and that the app is still quite young.
