URGENTLY need someone for Wordpress site maintenance

We are looking for someone who is very skilled in Wordpress coding, who can log into the back end of our site and fix some glitches. One of our booking forms isn't working and another contact form is loading very slowly. We have a launch planned tomorrow so will need to get this fixed in the next couple of hours. (2PM BST) We will also need a video updated. The live site is: www.paradoxhousecreative.co.uk
