So if I want to open up a business of some kind and produce a product (it can be anything from canned soup and stew to, chocolate covered fruits, to even beer or non consumable products). Where do I get the machinery for my factory? Where do I get the cans to put the soup in, and who do I contact? Where do I get started?
Perhaps if you are asking those questions you are not ready to get involved in this industry.
However I like to encourage people to follow their dreams.
First of all, if you are have unique products that you want to package and sell, perhaps the place to start is not a factory. You will be looking at a huge capital investment to get all the equipment. You probably could get a lot the equipment second hand. You would also have to register and make sure your business is compliant for food handling etc.
You may be better off starting by finding a company that would be prepared to do the packaging for you. You would be looking at smaller canneries who have some spare capacity.
Sure your profits may end up smaller but your risks are lower. Basically you would only need to pay for the setup costs and the first batch. If you run your own factory you probably have huge debt which could tie your business down.
The smallest you could start is home packaging (people make jams or chutneys and sell in markets) before moving to a more industrial scale.
