Over the years, I have had a pretty good experience with the Envato marketplace. I searched for a job portal and handpicked two of them for you just to give you an option.

They have all the features a job portal requires. But I personally recommend the second one I posted below. Because it's built on Laravel which is a strong framework to work with PHP language. It also has a premium plan option, so you can make money from day one.

It has a 27 minutes step-by-step installation video guide, so If you know how to work with a c-panel, you won't need any developer's assistance. And make your website live within an hour. Plus the price is genuine.

And the author/developer has released an update last month. So it's up-to-date.

First: Job Portal Platform

Second: InfyJobs - Laravel Job Portal Script with Website
https://1.envato.market/3Pk0KB

With this portal, you can make your project live with minimum cost and as early as possible.
