I'd start with something like:

class RateCard
  belongs_to :business_person
  minutes    :integer
  price      :integer #in cents

  def dollars; price/100; end
  def cents; price%100; end
end

class BusinessPerson
  has_many :rate_cards
end

<def tag="view" for="RateCard>
  $<view:dollars/>.<view:cents/> for <view:minutes/> minutes.<br/>
</view>

Then I'd add permissions, validations, view hints etc. to have it work
properly.
