Hey Dustin, thanks for the inquiry. Sorry you're experiencing this issue.
Unfortunately, from Clay's end we don't a direct solution for this because those limits come from Apollo and it requires waiting a bit to continue. They also have a max limit of 2000 calls per day, so it could take some time to get a larger list using this API service they offer.
The best workaround would be to download the list from their site to then continue enriching within Clay if they volume you're looking for is larger than what the limits allow. Let me know if you have additional questions!
