I have some ideas for 2 new jobs (or money making things):
1 - Garbage man. The player has to get to the junkyard then type /c garbageman or something similar, then he needs to find 8 dumpsters (I can't find more than that) around Little Haiti. If it's possible, we can put a trash bag pickup in front of them, if not, the player will simply approach the dumpsters and type /c collecttrash. The player gets like $10 / dumpster. Then he gets back to the junkyard and gets his payment by typying /c offloadtrash. And, of course, this job can be done once at .... 8 hours.... to avoid getting money too quickly (that would be just very unfair).
2 - Money counterfeiter (sorry if I got it the word ,,counterfeit" wrong as a noun): The player can buy from the docks some cash plates ($1, $5, $10, $50 and $100). As soon as he buys them he becomes wanted (to avoid unfairness, the job will be available only when there is at least one cop). After that, he gets to either Print Works interior or the underground printing machine (the one near Phil's Place in Little Haiti) and types /c printcash. The next thing might be hard to script but I am just saying: a message like this will result (depending on the plates): ,,You've printed 10 bills of $100 and you've got $1000". This thing results in a script multiplication. To have a successful session, the player needs to go from the docks all the way to the printing machines and back to the bank. Once he enters the bank, he passes the job, but he's still wanted of course. As with the garbage man job, you can do it once at 8 hours to avoid money farming.
