Simple Wordpress Modifications

I need someone to make a few small changes to a site, I just don't have the time to do myself.

I need an image slider changed to include frames/borders and add a social media icon to the footer with the rest.

I also need the Lightbox images changed to a bigger size at the moment when you click they are still thumbnail images.

I know this shouldn't take someone who knows WP more than 2 hours and that is being generous!
