Amend a wordpress website

i have a website at http://www.janinewhitling.com.au. I need somebody to help with redesigning the galleries. My usual lady is out of action for over a month and suggested this site. Basically the current gallery is not user friendly and this is the request i'd sent her that i need done: Could you please change the gallery to portfolio 4 template just like this ([login to view URL]) I’d like this to be a dedicated Art Gallery with subheadings of • Paintings • Installations • Mixed media • Works on paper • Other works I’d like a second gallery called Jewellery with portfolio 3 template and with subheadings of • Bracelets • Rings • Brooches • Necklaces • Other Can anyone help please. I'm hoping to have it done within a week or two at the outside. Kind regards, Janine
