SQL Query help needed ASAP.

I need some help with my below mentioned SQL Query. Per my clients request, they ONLY want to print the PatientContact info when the relationship is either "Guardian" or "LAS".

Here is the twist. A patient can have many contacts ... they can even have one maked with "Guardian" and one marked with "LAS". The great part is if they have one maked "Guardian" and one marked "LAS", they only want the one marked "Guardian" and omit the others. If they do not have "Guardian" and only have "LAS" they want that one and kill off the others. If a patient does not have either "Guardian" or "LAS" they want the Contact First Name to read as : "No Guardian or LAS Listed in Contacts".

Basically, they want "Guardian" first ... if no "Guardian" they will take "LAS" ... in neither just print that comment.
