Editing a coded website

I need someone to perform edits on my website, the website is coded ( doesn't use a platform like WordPress ) so you'll need to edit the html/css/java code in order for the website to get edited.

The edits are simple, we just need to add more projects on a projects page (some projects already exist), add some logos, and stuff like that, there's no page building or section-wise edits, as the edits are mainly simple.

I need this done in less than 24 hours.
