Horizontal Layout

Very new to this so forgive me for being a newbie.
I am trying to layout a contact form next to slideshow (plugin slideshow 2.2.3)

If you look at this link

http://etherna.themeforest.designsentry.com/contact

you see the form next to the map image, this is the layout I would like but where there is the map i would want the slideshow

I only seem to be able to get my slideshow under the form.
I have tried some HTML ideas I searched online but it either doesn’t work or messes up the formatting of other parts of the page.

Any help would be appreciated.
