Payments/Credit card issue

Hello,

I have an amazon store where I work with some local stores and sell the products via my amazon store. The thing is I am a student and I have a low limit credit card. I am able to make 700$ in sales every day but the limit is limiting me because I can’t buy these products every day because of the low limit and also can’t use my debit card because my parents still pay for my rent&college etc… Since Amazon usually pays the money I made from those products in 2-3 payments(usually 1-1.5 month to obtain the money I made because of account reserve etc..) I can just take the money pay the credit and do that in a loop. Any recommendations on how to solve this or is there a way? Maybe a high limit credit card but as I mentioned Amazon usually pays the full amount in couple of payments therefore I don’t know how I will pay the credit card before those deadlines. Thanks.
