Hi Waffel,
It's great to hear that your biz is successful. I might suggest (depending if you have the time to invest) starting a side online biz. I suggest this because online biz's are a good way to build money quickly as well as being convenient because your working from home and that leave you time to attend to your main business while you work on building fund with your online biz. Loans could be another option, but I don't recommend them because they (in my opinion) they really do nothing for you besides get you into more debt and cause more stress than you need.
There are many different business to invest in, some better than others. I'm currently involved with one that requires very little money investment, I offer to pay all my new business partners way into my biz ($47) value. I think it worth taking a look at because of your current situation it my be a big help and provide a solution to your issue w/in short time frame.

I wish you the best.
To your success...
