Integrate Different Setups (.exe) Into 1 Setup File for Windows

Hi Freelancers, I am looking for a qualified coder who can do the following: I got 4 different setup files for Windows (.exe) and I need them integrated into 1 Setup file. The new Setup needs to be able to download the single/smaller setup files (.exe) for any given websource (http only) All 4 smaller setups must be downloaded and executed, one after the other untill all Setups are done/installed.
