Hi there,
I can do this job for you. I can redesign and update the donate button on your weebly site. I will just use the css to update it, will not alter the html, or scripts, neither the original source of that donate button.
Yes, I'm fully aware of weebly sites and their working process. I have created sites on weebly cms before. I can show you my live work Samples, if you need.
Feel free to discuss anything regarding this project before starting.
