Getting my own authority

Good day all,
Just looking to get some advice and information from anyone that can offer in regards to getting my own authority
I've done some reading on a lot of forms and majority of the posts repeat themselves
Just a little background info on myself. been on the road for three years now
Drove for a crappy company. I got my CDL issued from for about a year as a local container City Driver then switch to container cross border Canada US and then finally switch to 53-foot dry van after 6 months
By my second year I took a $35,000 Canadian loan from a family member to get my own rig on the road purchased a 07 vnl 670 with a Cummings ISX had about 1 million kilometers on it when I got it spend some money to get everything roadworthy as everyone that purchased a used truck the first year was a b**** considering the company I was working for was only paying 131 Canadian loaded and gave low mileage runs which made it hard to maintain truck payment insurance and could barely afford maintenance
Did my time on the road with my own truck changed clutch turbo Etc But we've gotten to know each other well now and get along fine
First year had to sleep in the winter under 3 blankets cause there was no money left for a bunk heater after expenses other than a plug in blanket because I couldn't afford to have the truck running all night and wear down my engine
Left that company after getting my two years experience and pulling for a somewhat decent company now because they pay a lot more with a seventy-five 25% split
But at the end of the day they are extremely unprofessional and just a bunch of young guys sitting behind a desk trying to get rich buy Trucking and don't even give two s**** about their drivers or the risks we have to take to fill their pockets
Have experience hauling 53-foot dry van to the Midwest Florida mostly Eastern Seaboard including all over New York City Bronx Brooklyn Manhattan also did some flatbed concrete slab runs from Ontario to Boston liked them
Actually managing to save some money now and truck is running great at 1.6 million kilometers
The purpose for my posters obviously with working for a trucking company with a split we all know they are not giving us the 75% of the load amount and constantly cutting the raid stating that they're not getting paid as much but more importantly these guys have me pushing night and day most of the time with no regard for hours of service or rest.

Was looking to get my own authority as I do have plans in the future for putting a truck or two on the road to start and figured starting off pulling loads for myself would be the best route look at that experience before getting my own drivers
Which is why I put myself behind the wheel of a rig to know the life that we have to live in the sacrifices we made instead of just going and trying to get a loan to start a trucking company up as everyone else does without knowing what we have to go through on the road
I figured instead of giving the company I'm pulling for 25% which averages out to 5 to $6,000 a month I could put that towards my own authority and having three trucks on the road and giving them 25% adds up a great deal
I'm well aware of all the procedures ans everything else associated with getting my own authority in Canada and for cross-border the question I have is what do you guys think would be the best cargo to haul and what equipment flatbed tanker reefer and what locations to pull to and from, based out of toronto ontario canada

Just doing some planning ahead of time now looking to have enough money saved up by the end of 2016 to go out and get my authority so I need advice or things that I should look out for it would be greatly appreciated any advice on great brokerage sites or load boards that anyone has had experience with best regards
