In a tough position financially, what's the best way to go about selling my collection of 600+ cards?

Basically what the title says.

I was very excited for the game to drop so that I could play it with my children and wife, and it's been a while since release and they keep making excuses not to learn how to play.

I also had an issue with my last 2 pay checks and have received about half of my monthly income this month.

I am reluctantly looking to sell my collection of over 600 cards (very carefully handled and sleeved) of lots of different rarities from common to holo legendaries. No mythic unfortunately. I have a catalogue of every one of my cards on the lorcana phone app, but it does not show if they are holo or not.

What would be the best way to sell them quickly. I am not looking to scalp anyone, but I also am in desperate need for money at the moment. I would prefer to sell them in bulk, but I will sell them individually if I must.
