If you haven't run a botfarm before I suggest you to start with something that you can't really lose any money from. Such as making tele tabs as you already mentioned. Once they are 99 magic you can also sell them here on Sythe for around 30-40M each I believe which wouldn't be bad. Starting with around 5-10 accounts for a month until they are all 99 magic would be nice. If everything works out you can invest into a VPS/server and run more bots doing different things.
