Solidity expert - BSC / ETH Bridge - Multi-blockchain coin launch

I am looking for an expert in solidity. We have already launched our coin on BSC network. We now want to launch it on eth and would like to bridge it somehow? we want people to be able to purchase our coin on eth or BSC and it somehow maintain the same price if possible?

We also have a new coin that we want to launch on ETH and BSC at the same time using the same method. If you can help with this, please bit and i will be in touch
