Long snapping resources

I love long snapping and it’s one of my niche abilities and now that our starter graduated (he was on the field the whole time), I know that i need to get my head right and start pulling my weight however there is a lack of coaching for this type of thing where I am at.

If it helps, afaik I just lack consistency and on punts sometimes it’s at his knees or feet.

I’m just looking to have resources available so I can improve before the season starts. Any warmups or routines are good too
