You could try submitting the transaction's ID to this service at the start of each hour and hoping you get into the 100 free slots allowed each hour. Afterwards the viabtc pool includes the transaction in the next block it mines. However, competition for the free slots is so intense that you have to click the submit button exactly on the hour, a few seconds later is too late.

As your mycelium wallet is the receiver you can create a new wallet in electrum using your mycelium wallet's seed words. All your mycelium addresses will then show up in your new electrum wallet.
There's instructions explaining how to do it in this thread.

There's a guide explaining how to do it here.

Viabtc also provides a paid service, but it charges 0.01BTC for each transaction which is over $20.
I faced a similar issue a few days back transaction not getting confirmed due to low fee but user "QuickSeller" got my transaction confirmed in minutes when I sent him 0.0001 BTC. He has access to some pool . PM him.
