Yes these steps are good.
but one thing is that- you don't need to go any company to check the car, you can go to any car computer checkup at salwa road any check the car.
but i am wonder that you can get a good car at that amount.
you may find nissan sunny, honda civic, toyota corolla at this price. but you must have to be careful. one of the most important thing that you need to know that the seller who is selling the car : what is the reason? he is leaving the country/ bought a new car. because many people sell their car when they have many problems coming on their car.
so see a low mileage car and ask the buyer why he is selling? he may be angry sometime but don't care...
good luck!
