Your idea is very cool. I would also like to see this sight. For my wedding, which was a year ago, I released 10 thousand balloons into the sky. I have a wedding video that I still love to watch. At this place, I ordered balloons last year. This site https://www.fastballoons.com/en/content/85-how-do-i-inflate-balloons-useful-tips also has a guide on how to inflate the fast balloon yourself. Have you ever ordered heart-shaped balloons?
