I got a free server machine and I’ve done all my plotting works.
I currently have a capacity of 20+ plots per day, with a 1Gbps network. So if someone is interested feel free to contact me so we can discuss further terms.
For technical details, I can setup a samba server for you to download the plot, and I have a script for you to automatically download all plots from the samba server. You just need good connection and have your download machine on all the time.
If you are interested, you can contact me. For new users, I can make 3 plots for free, just let you try the service.
