Hello Mr/Ms,
I'm a web developer for about 3 years, working with node, react, mongo and others. As I'm full stack, I can handle the front-end required to finish your script within a few days. I have done these kind of scrips before, but be aware you would have to have your browser running.
As I believe you want something complex with settings and features, my bid currently is $700. We can negotiate through chat if you're interested.
Thanks,
Lorenzo Fontoura
