We do not permit overt advertising in a post but your post, above, can remain as a direct response to a question on the topic. You could, however, provide a service by posting examples of costs at various ages and typical coverage and restrictions; generically, without identifying any commercial agencies. Those interested might then contact you by PM or Visitor Message system.
