How to find a gig writing additional music?

Does anyone have any tips for successfully finding and picking up additional/ghost writing gigs?

I know a lot of people are gonna to chime in and suggest assisting first, which I’ve done (as well as some done some sporadic ghost writing). I feel like I’ve got a solid demo reel, a decent set of credits and have had some positive response from people I’ve reached out to (To the point of people saying, “Yes I’d love to work with you, contact me in x amount of months when I’m gonna need help and we’ll figure it out), but nothing seems to pan out and I’m having trouble diagnosing where I’m going wrong.

Just curious if anyone has any other ideas or methodology!
