GTA V Money Drop Question

I recently decided to play GTA V on PC after getting it free from Epic Games about three years ago. I'm just wondering how I can get money, as it's a lot of effort doing heists, jobs, and playlists. I want to buy a house, make a good-looking garage, and buy all of the weapons I'm currently missing, which is about 95% of them.

Is it worth buying an alternative account and giving a friend my main account so I can use a mod menu for money drops and levels? I got given 400k randomly in a public lobby and have had no luck finding any moderators since then, as it was my second day back on the game.
