A few tweaks for my wordpress site

I need a few small jobs done to fix up my wordpress website; 1. the drop down menus disappear from the headings in menu bar so you cannot click on them. 2. there is 1 space line in my footer that i want to remove (under all the icons) 3. i need my website to be compatible with macs, ipads and iphones. 4. on this page - [login to view URL] i need the plant profiles to be not spaced 1 line apart. 5. on this page - [login to view URL] i need the contact image to sit to the right of the contact form in the empty space. 6. on this page - [login to view URL] i need the bottom paragraph removed, everytime i try to do this the page alignment shifts. this should be the last line on the page - Online Garden Design Service Regions – Australia Wide Landscape Design.
