A lot of it comes down to confidence really. You gotta ask yourself... do i have the cash if things go tits up (which it might)? is my job secure? Those are the singlemost important things you could ask yourself when taking this sort of thing on. If you answeres were yes then, yes go for it mate! Its not as hard as you would imagine, bullert-proof your luverly lump and simply bolt on, and fuel manage it. With the right contacts you could make your dream come true, providing you could finacianly support it. good luck mate.
