Hi Gerry,
be careful with these "expensive" rugs. With regard to price you are going to have to prove your professionalism to get 10% - you will need to explain clearly the cleaning process that you are going to use - I suggest you take a dye test kit - and do the test - that always prompts the question "what are you doing" - then you can reel off the patter. Aslo make sure you only use Woolsafe Approved products (if you can clean with an alkali cleaner).
Make sure your Treatment Risk Insurance covers you for the value of the rug you are dealing with - get the customer to tell you what it is worth. Also make sure that the rug is covered whilst transporting it - don't leave it in your van overnight.
Examine the rug very carefully - both sides and note down any damage that you see - worn fringes, worn pile, stains - whatever. If possible get a dig photo before you even move it.
Get the customer to agree/acknowledge the damage and also get the customer to sign that the cleaning is done at his risk - try not to carry all the resposibility - especially if the rug is going into storage - you need to get it signed off when you have done the cleaning - not in a years time when it comes out of storage!
Personally I would do the rug cleaning myself - I don't like passing it on to a third party - you never know what they may do - remember your contract is with your customer and it is you that they will be gunning fopr if it goes wrong or missing.
Good luck!!!
