Seeks advice for business opportunities/ managerial, PR jobs

Dear friends,
I am a PR card holder and i might land again in 2013. I am having 15 years of experience in media field in India and 4 years of simultaneous experience in a Managerial post in the Gulf.
I would like to run a firm of my own or lead a team in a reputed organisation. I am not interested in continuing in d media field as the work is so hectic and lost the thrill after working for one and half decade. But one thing remains- instead of writing and editing, the passion for photography!
Can any one of u suggest suitable fields for me in the ontario province?
If i have to start a business of my own, how much minimum investment is needed? Is there chances for getting any financial aid from banks for freshers?
Or should i opt for managerial opportunities/ PR options? R there any chances of getting a highly paid managerial / PR job in the same province?
Thanking u in advance
