The Stardew Valley Joja run : What is a good strategy to optimise the cash early game so that run is done as fast as possible?

I'm picking up the last few achievements in Stardew Valley, and I'm getting to the one I dread. The Joja run.

I've often heard that doing this run is really sad because, well, instead of building up and fixing stardew valley, you are destroying it.

So I want to make it as short as possible. What are some good strategies to make the 140k G as soon as possible so the run is as short as possible?

Sadly, by update or because I'm playing multiplayer, PausePause's plan did not work. But the bases are there.

1. Start your farm and give yourself a name with the item glitch. I personnally didn't like the Stardrops, because as soon as you go over them in inventory, it uses them. So I went with 3 5,000G items.
2. Go talk around the town. Pierre, Caroline and Marnie refer you by name in their first talk, so its gonna give you 45k right there.
3. Mine stone and wood. Build a coop ASAP.
4. In multiplayer, have one player go buy chickens, with the items glitch, and the other stay in the coop and sell as soon as the chicken appears. (In solo, I guess do it by batches.)
5. When that is done (we got 250k in a day) then you have your 140k for the projects. Go talk with the Joja Guy.
6. The membership card and upgrades can only be done 1 per day. BUT, in multiplayer, if the upgrade menu is open for 2 or more players, they can each select an improvement and it will be done (so you can do 2-3-4 upgrades in the same day.)
7. When all upgrades are done, go to joja mart, get the cutscene and the achievement.

We were done Year 1 Spring 10th.

Name your character [434] and repeatedly speak with Gus in the bar during your first day in the valley. The game handles these codes as items, and any time the code is read the item is placed in your inventory. Gus says your name every time you speak with him during the first day. So each time you speak with him the game will give you the item with the code [434] (which is the Stardrop, valued at $7,777).

If you miss this opportunity, you can use this technique to name a farm animal (once you're able to acquire farm animals) and reap the rewards in the same manner.

Other viable Object Ids would be [163], [166], [279], [439], [896], [900], the codes for the Legend, Treasure Chest, Magic Rock Candy, Purple Slime Egg, Galaxy Soul or Legend II, all those sell for $5000. You can give your character more than 1 object id as a name, and get more than 1 object at a time while talking, so combine them.

This glitch has been patched out of the console version of the game, but if you're playing on PC this should still work. You can read more about the exploit here
