Editing and revision of sites on laravel

There is a task to finalize the existing site, the cost to estimate in advance
its hard enough. Because it takes several hours to
understand the code, the site is in a docker container of 4 parts. I.e. only 4
docker: home, landing pages, blog, translator.
You need an experienced developer, I am interested in cooperation by the hour.
Well, or a fixprice if you can estimate the volume on the current tk without
prior access to the site.
