Im going to have to do the same process again but this time for a bigger transaction

How big does the transaction fee need to be if the transaction is approximately 50mbtc ($5000 usd)?
Since the first one was confirmed due to being included by ViaBTC's free accelerator:
You can also do that with even less fee than the previous transaction if that new transaction will only spend about 1 to 3 input(s) and 2 outputs.
Precisely, the new transaction should have less than 500B in size and at least 10sat/B fee rate to be qualified to their free accelerator.

Although Electrum computes the "virtual size" (vBytes), your Electrum wallet is the old 'Standard' version with legacy addresses so the virtual and raw size should match.
If it's a different wallet with SegWit addresses, the virtual size and actual raw size will be different so the "sat/vB" that you set will be lower in "sat/B" and there's no way to see it in Electrum.
So when creating that new transaction, keep track on the size and fee rate to be eligible, use "coin control" if necessary. (How to coin control in Electrum)
Then submit it to their free accelerator or ask users to summit it for you (requires the TXID).
