I actually admire that bravado in people who can walk the walk. I'm not a fan of false humility.
All that being said, you seem to wear the solo-founder badge a bit too triumphantly. I can't comment on the superiority of your solution versus competitors but I'll bet you can hold your own. Getting someone on board who can SELL your story, and communicate your product to interested buyers would probably do wonders for your sales if you found the right guy.
Trust me, I see where you're coming from. After a bad past experience myself, I am now a single founder building up my product in solitude. But I know where my limits end, and when my product is ready to go to the next level, I'll have no problem bringing on a VETTED and qualified partner to grow the company as fast as possible.
Just a thought!
