trying to figure out how to get usdc off of bsc

I'm going crazy trying to figure out how to get 50 USDC off of BSC since I have no BNB on BSC. Can anyone help me figure it out? So the problem is that ETH gas costs are so high that the cost of buying BNB on ethereum network, then bridging it to the BSC network just to have BNB to pay the gas to get the 50 USDC on a bridge to another network, preferably Polygon, is prohibitive. I probably just need a couple of dollars of BNB moved onto BSC. I'm in the U.S. which makes accessing getting any funds or crypto onto binance much more difficult, even with a VPN. I'm only familiar with polygon and ethereum chains. Can anyone help me figure out a way to get a couple of dollars of BNB onto BSC at a reasonable cost to get my 50 USDC off?
