Help how do we start an immigration (Calgary)

Hi guys

My wife and I would like to look at leaving the uk for Calgary. We have done quite a lot of research and are coming over for a holiday/scout in September.

However ,,, this is a huge step and we would like the help of an immigration lawyer or someone similar. Does anyone have any advice or people that they used back in the uk that you could suggest?

There are millions on the internet but I thought there would be a good starting point to ask someone that's already done it.

Thanks in advance guys

Michael
