CSS file update on Responsive magento web site

Hello I need an helping hand due to lack of time on my Magento Web site. Jobs : 1 - You need to transform some datas in a CSS file to let my logo get smaller when my store is displayed on a mobile phone or Tablet. 2 - You need to fix my jquery /css carousel not working properly when reaching the last pic (same than on themeforest, search for preview/ theme called Trendy number 3409832) 3 - You need to fix the position of the search container, not displayed nicely when watching the web site on Mobile or Tablet. You might need 5 hours to do this (that's what it would take to me) Thanks for you bid. Good luck Cheers
