I think there is a logics flaw here.

By all means use the "girls site" to promote your "design site". BUT keep your "design site" free of the "girls site". i.e. let the girls drive customers to the design business but do not mention the girls on your business site.

Your front page is cluttered with information not needed to "hook" your customer.
Keep in short and sweet - details should come later.

Golden Rule: Never mention money in your starting paragraph, unless it is below $9.99

In addition, you have some typos there too.

Offer customers a choice (set out in table form) on another page.

I could go on and on....
