WAGZ,
Starting any new business does require capital. Not just enough $$$ for setup and stock but enough to operate on until the cash begins to exceed the overhead. Thats basic to any business.
I think its great for anybody to do for a living what they love to do. Enjoying your work is one of the keys to success, especially in owner-operated enterprise.
One way to beat the high start up costs is to explore buying an existing business. You may have to pay for "good will" but usually you can get the equipment for a deeply discounted price and there will already be a customer base. This too, requires some serious research to make sure that the books are accurate, no tax liens, etc, and why is the owner really selling?
I wish your brother success.
Dick
