i feel like your suggestions will come with time, but as for your specific situation you may need to start greasing the game and setting yourself up to be busy in the first 5 or so days without touching a single satellite.
Method to get money (slight spoilers ahead)

Start the game, walk to base or debug tp with "." on numpad, collect the open trash cans around the base, 2 are directly outside the front door, 1 is in the garage, 2 are by the radio tower, and 1 is by the transformer behind the base (where the workbench is) these trash bins have their own carry weights of 300 and some change, so you can hold them in your inventory, and by proxy also store them inside of themselves (Edit: The carry capacity of the bins is around 1200, so you can store multiple bins inside of 1 if you really needed to). Use this method to gather 3 trash bins in your inventory, get on the ATV in the garage and head out of the base to the right, follow the river until you reach the tree trunk sticking out of the left side of the river bank, climb into it, remove the 50 MRES from the barrel inside, store in the 3 garbage cans, climb out, go back to base.
To get the points to sell these you can wait for servers to go down inside the base, or you can go to the bathroom attached to the bedroom/kitchen upstairs and clean the shower/sink/toilet with a bucket of water and a sponge, lots don't know that doing that and unlocking the achievement actually nets you points. The MRES by themselves will easily net you over 1 thousand dollars, and then from there you can buy trash bags and a woodchipper or whatever else to sell all the trash from inside your base.
Apologies for this long winded ass tutorial but this game is weird as shit so I feel like I have to be ultra specific. But this is essentially my method of playing every single time I start a new save, which is for basically every single version that releases at this point.
