Styling & simple code updates needed ASAP for wordpress site!

General information for the website: template based website
Kind of development: Customization of existing website
Description of requirements/features: I need the following doing ASAP:

1. Some simple code changes to wordpress pages
2. 5 buttons creating with hover over version (I can give you the existing button design just needs copying and text changing), then putting into the relevant pages
3. Need our chat/conversation page re-styling to look more like the attached example

I can provide all logins to wordpress back end and also the ftp. This is required in the next few days, shouldn't be more than 3-4 hours work max for a skilled developer.

Any queries please let me know.
Extra notes: This is required by Sunday night so need someone who can work fast and efficiently. There will be more work available on this site if this goes well, looking to build a long term relationship with a good developer.
