Write some Software & create online store

- I want to build website "Online store " in order to sell several products with many categories - The way we'll sell are "Tree Marketing" - "Tree Marketing" which mean that every one will buy a product he'll have his own code & if he suggest some one from his friends by his code he will take a commision . - I have the system on my mind , commissions & relation between customers will be thousands and millions in some levels. we will discuss together & Explain in details. - "Example for tree marketing systems" If the customer invite 5 persons to buy, so we have 5 persons in the first level & the customer will take commision on the 5 persons also, every one of them will invite 5 persons ,they will take commision for their new buyers ... Etc, so 5*5 in second level 5*25 on third , 125*5 on forth... Etc. - System also should be flexible for getting reports for administration to control, also ability to make profile for each customer. Required strong website with very strong system with high security because as you see it will calculate a lot of money & customers
