Tidy Up My Pricing Plan Grid

I am trying to put a pricing plan on a page in my Wordpress site.

I am using CSS3 Web Pricing Tables Grids plugin.

I have a css problem. The table has a white background by default and my site has a black background.

So the table looks awful.

See here: - http://www.capabilityevents.co.uk/18th-birthday-party-examples/

(PPH do not remove this URL please - Freelancers need to be able to see it to be able to know what needs doing. Without this URL they cannot possibly quote)

Note that this page and form are work in progress at the moment.

I need someone to tidy it up and to make it work properly.

Other little jobs are:-

1. Make the button at the bottom of each plan link to another page. I just don't know the short code to make this happen.

2. Sort out the H1 and H2 tags. Clearly the pricing plan is taking it's font and H tag from the theme but this messes up the plan and makes it look awful.

Please bear in mind.

I have no idea at all about CSS. I know it exists but it makes no sense to me.

I think this should only be an hours work really. (correct me if I am wrong)
