How do I get the funding to start my own shutter making and fitting business because at the moment I'm capable to run 1 I just need the cash for my first lot of supplies and a van and unit to work from

Go to the bank and get a loan ?

Get friends to invest in your business.

Start with a cheap trailer behind your car and get part of the money as a deposit for your first job for supplies

If you can't get the money now, find a second job and save up for what you need.
