I have been going around google trying to find a decent app to help write proposals since I can spend up to 2-3 hours writing one.
An acquaintance of mine pointed me to http://webproposalgenerator.com/. It's still in it's early stages and still on going development but the nice thing about this is that I don't have to sign up for anything. It install just like any CMS like wordpress and it allows me to send the proposals to clients for them to accept it. They are pretty good at support since a few features that I recommended has been implemented almost immediately.
Anyway... just thought I'd let people know about this. If there are other proposal writing applications out there that you can recommend me, lemme know.
