Build me an automatic Openvpn changer

Hi, I can do it in one day. But just tell me what is your OS (win Mac or linux) are u planning to sequentially switch ovpn files? or create new ovpn on demand? just be little more specific about input and output.. i assure u will have a swiss level execution in a day.. Regards

I can do this in few hours. All I will need is your operating system and if it multiple platforms, let me know. I can write it in nodejs and python.
