Bill, price wise it is so small you should just charge whatever your minimum is. Each to their own but £35 is just way to cheep and not worth taking on. By the time you go to pick it up, bring it home to clean it and then take it back I wouldnt do it for less than £100.
Anyway, Kilims are a bit of a pig to clean results wise. I say this as they just dont clean that well.
They are usually multi-coloured and all out of shape. Not as bad as a needle point but still out of shape. Chances are you will change the shape again but this is normal and not worth worrying about.
They are such a short flat weave that you should be able to remove all dry soil by air or beating or however you de-dust your rugs.
They will take flooding so clean it that way and you should be fine.
Best, Dave.
