Business/living

Hello Everyone,
I'm looking to move to Bavaro/Punta Cana area from Ontario Canada. I lived there for three months in a condo. Fell in love with the culture and the people. I travelled to a few places in the Dominican but loved Bavaro.
I'm not looking to hookup. I am aware of "the sanky panky" and the dangers😉
Looking to open a small business and somewhere away from the cold.
I do not speak a lot of Spanish but hoping to learn enough to get me by the time I'm ready to make the move. I feel this area has enough English speaking people it would be an asset for me to live in this area.
I was wondering if anyone could give me information.
1. How much a cedula would cost to get in 2017 and how long is it good for?
2. How much will it cost to get a small business incorporated ? I have looked on the net but couldn't find anything past 2011.
I realize I still have a lot of research to do and want to do everything legal.
I'm not rich by any sense of the word but I have had and ran a successful business here for 20 years.
Any info would be Appreciated. 
Thank you for time. ☺
P.s hope I wrote this in the right space.
