Going out on a limb here and assuming you want to be vollyed (hired back and forth) to earn money and upgrade. Being volleyed is not the most effective way of making money. I would recommend partying for money. To party, join a club, and hit the party. If you can, I would recommend joining Cat Cafe or Pizza Pop (Art) because they pay the most. You will get money once the party is successfully completed. A club I would recommend checking out is first things first. Once you earn the money, and probably before too, check out some of the threads in the strategy section of forums This guide explains how to get started I'd check it out first. Also, if you need help or more suggestions feel free to ask me.
I should have posted in forums asking for help when I first started. My old pup told me that volleying was the only way to make money to upgrade. He said that the others didn't make near as much.
You volleying WITH someone else and having them keep the tut IS a great way to earn money. But good luck finding someone who wants to give you money out of the kindness of their own heart.
A volley isnt the most effective way to earn money...partying is join a b2b party club and party and be loyal
