Need a expert level Python or Bash Shell scripting developer This is a brief overview. Every organization has some basic security baselines, such as default user/pass should not be there, default sites should not be there on the browsers, default service should not be running on each server etc. Similarly we have such security standards with servers such as IIS, OS, Web server, Linux, DB servers, network devices, there is a baseline security standards.

I'm looking to create desktop software that vectorizes any image uploaded to it. I also want to take any colors that are on the original image and for each color create a separate layer. It should then output the files in .SVG format. I want this program to be desktop based, and have a user license that requires a monthly/annually updated serial code. The software will check if the subscription has expired, if so, it will not be usable unless the user goes online to pay for an additional month/year subscription. Let me know what you would charge for this project. Let me know how long you think it would take you to complete the project.
