Multiple Q-in-Q (Q-in-Q inside Q-in-Q)

I have searched this thing before asking here (Google and this forum) but did't find relevant result.

I would like to know which type of Cisco switches that support Multiple Q-in-Q (QinQ inside QinQ)?

For example, I have 1 Gbps Q-in-Q link from a network provider to connect two switches located in different town. Via this link, I also will re-sell a small bandwidth / capacity to our customers which they also require Q-in-Q, so there will be Q-in-Q inside Q-in-Q. Which type of Cisco switches would be able to do this task. I know that Cisco 3560, 3750 supports QinQ but are they able to do multiple QinQ ?

Thank you and appreciate for your answer.

Make sure that the MTU supports it. I don't think there should be anything stopping you from doing it as long as the switches support a large enough MTU.
