I would take a break. I find on a holiday without any link to work that I get most of my ideas.
Go away, relax and put it out of your mind. And while you there read books by Napolean Hill - think and grow rich, Joseph Murphy - Power of the Subconcious mind and other motivational stuff.
I eventually closed a business that had potential because I ran out of ideas. Looking back if I had taken the time, reaearched the market and realised my quality of service was poor I could have turned it into something. The market was ripe for picking. But becuase I was at the boiler plate for so long I could not see the forest for the trees in front of me.
Try also see if you can go ahead without the money. Any good business doesnt just need money, it needs sales. If you not selling enough the extra money is only going to dig a hole deeper than the one you in.
All the best.
