Infinite Credits

After the quest is complete, you will get a discount from all the goods she sells. Start selling her all of your expensive equipment. Then, travel to the Wards Markets, and talk to the merchant named Expat. You can buy all of your items back for cheaper than you sold them for.

Return to Dr. Michel, and sell her all of your items again. Repeat this process as many times as desired.
