Hi there, I understood your requirement, I can create add button to job website for posting to stay longer. Currently, it is 30 days and one price. I want users to have another button option to have 60 days and a different fee when they check out as the way you need it, I am an experienced full-stack developer who has been working for the several years.
I would like to discuss more on your project via chat so, I can share my expertise on your project, feel free to ask me any questions and be sure to get reliable communication from me.
Regards,
US
