You can borrow money to start a business but the lender will always look to how they will get their money back. The usual way is that you guarantee it by offering a charge of your property etc.
If you have no way of raising the money yourself or of offering security to the lender then I'm not sure what youre contemplating is feasible.
Isn't it possible to start in a smaller way, without an outlay of �100k? Have you done a business plan to show that your enterprises would work and be profitable? I'm not an expert by any means on either of the markets you mention, but in both of these you would be up against some seriously big competition.
