My mum produces homemade liquid dish-washing soap (like morning fresh). It's of good quality - it's thick and smells good.

At the moment she has just a handful of customers but according to her it's because she hasn't been producing in larger quantities. I am interested in partnering with her not on a mum - sun basis but as an investor. I have limited information about this business and would appreciate any good advice on this business. Also, she suggests that with an investment of #10,000, the business can generate enough returns to survive which I highly doubt considering that we have not included logistics cost to it and with the fluctuating currency, it's almost impossible.

For someone with experience in this line of business what is a better estimate of minimum capital to start with?
Also, I know they sell the chemicals in Ojota but does anyone here have a recommended seller, someone I can trust with a good price?
Any automated method for making this liquid soap available, cost and where to purchase it?

Please I welcome only good advice. Thanks
