Refining the self-written site piece by module

We are looking for a freelance PHP programmer, Mysql with experience in working with foreign and not always logical code.
Small volume of Jquery, layout html, css.
They're missing hands. We are a startup, so the budget is small.

The site Texte caché. Almost completely self-written. The structure is simple relative where we show it.
You have to look for files, sort out and do something like that. Comment on all adjustments and new code.

The specific task now is: Make modules:
Blog. Essentially news with image (adaptive size and processing) and design in CKEditor with convenient ability to download / add additional images inside. Add codes to videos from YouTube, etc.
Subscription. These blogs are so that you can subscribe to ordinary users and watch in the feed.
Comments on the blog post. Addition, editing. Simple enough, but with the possibility of an answer.
Likes for blog posts. Likes for all the products on the site. Counting, auto-replacement of the meter.
Nothing unusual, everything is pretty standard.

Photoshop models, you need to do everything exactly as they do.
There is very little to cut out if we can provide the finished material in this matter.

Time is always better faster, I think it's a few days, a week, mostly to parse someone else's code.
Payment will be saved, Yandex.money, well, or if we need to agree on others.

In the future, it is interesting to constantly cooperate in more complex, time-consuming orders for the same site.
