Rewards to the company staff

To reward the company staff because the great year of sales in the company perhaps we should know who were the best employees, maybe the top five of them, then i could know what are the preferences of this 5 employees and with base on that i can give them their rewards.

But the most popular rewards are a laptop computer because a laptop is personal and will be all of the employee's propertie and he could do whatever he wants with tha laptop.
Maybe he could sell it or use it in his work to improve in his production and in that way he will be motivated to do his best.

The flight tickets are a good option too because all of us wants to travel to rest of the job and the city and a help with the tickets it's a good incentive to our salesman.

One week's extra holiday would be an option because if they want go to take vacations one extra week be an important encourage to the employee or if they have family motivates them to work better and by that way they can have more time with their families.
