With what you are offering you are actually giving money away for something you can do for free. There is a lot of tx accelerators out there and the only thing you need to do is input the raw transaction id of the transaction you wanted to speed up. Here are some of the tx accelerators I know you can use.

How to get the raw transaction detail?
Go to https://www.blockchain.com/btc/tx/inputyourtxidhere and add "?format=hex" at the end of it.
Look at the https://coinb.in/ if you know how to use this then you know how pushTX works.
Anyway, As I said above I already rebroadcast it to the broadcasting sites that listed on the wiki link that I posted above and the transaction seems already confirmed.
