Seriously, if it scares the crap out of you and excites at you at the same time then that is a good basis to start from but you MUST believe in the "product"
Then why ask for any advice if you know all the answers?
i have answers, but no experience or knowledge in the area, i have for the last 15 years worked for other people, i have never been the big boss, and at the end of the day, those major issues have been someone elses problem.
i want info form people in that situation or who own their own business who might highlight things i haven't thought of.
will wait for more info from the company and if im more serious then i might book a meeting with the bank to find out more about figures etc and how it might work.
if i'm honest the thought of it scares the crap out of me, but i also find the prospect quiet exciting at the same time.
