Sales rep receiving commission

I would like to know about Network Marketing. I heard about a company from one of my best friends which sells products like kitchen items, laptops, smart phones, TV's, Refrigerators, washing machines, sofa sets, CCTV camera solutions and many more use full products. The products are sold at market price and in good quality with a warranty. The company is a government registered company and they pay income tax too.

1. If I purchased a product from them, I can be a dealer (sales rep) if I wish. Is it permissible in Islam?

2. When I recommend this product and start to selling it, I'll receive a direct sale commission. Is it permissible in Islam.?

3. When I achieved my target as a sales rep, I'll be promoted as a leader (supervisor). Then we need to help my reps to achieve their targets. If they achieve their targets, I'll get a group sale commission. If not, I won't get a commission. Is it permissible in Islam? Usually this is how a marketing commission scheme works. Sales executive, Senior sales executive and more promotions are also there.
