Saw someone on the services board offer this kind of service to users, although I'm not sure about his credibility or if it's even true.

Personally speaking, if you're looking to process a transaction ASAP why not just use a different network instead of bitcoin? I find that using other networks when I make crucial purchases more reliable and less stressful than having to wait a whole day for your crypto transaction to push through. But idk man, might just be me. I just don't see the point of already paying something to process your transaction faster, on top of already paying the corresponding transaction fee in in your crypto network. You're basically getting fucked sideways (just my opinion). Alright, Yapping over, go check the services board and discern whether the guy's honest or not
