Just trade directly using Decentralized Exchange if your money is on ledger. No one will trade you this small amount due to high transaction fee of both Bitcoin and Ethereum. Unless you are both willing to wait for a long period of time when using cheaper transaction fee then its possible. 6.5$ is the average transaction fee to confirm within 1hr on Bitcoin though so goodluck on this transaction.
Check transaction fee calculator here:
https://bitcoinfees.net/The optimal fee rate for quicker Bitcoin transaction confirmations actually dropped during this past weekend. Even 10 sats/byte can get one's transaction confirmed in the next block. That's approximately under $1 based on average native segwit transaction size.
The problem is still with ETH, 75 Gwei( 5 USD) which is high for the person who will be trying to send OP the ETH.
