Advice needed with AWS credits

I launched Universimm (entertainment app) and I'm using AWS Rekognition technology. I intend to use Neptune in the near future. My issue is that my AWS credits are expiring and I'm about to start an influencer campaign, but I can't do this, if I don't have enough credits. I need to apply with more than 10K credits to get more credits the 2nd time. I am hoping somebody from AWS reads this! I am using Rekognition and plan to use Neptune, so I really need these credits or this amazing project will be stuck! Please help :)
