I paid €120 to have mine cleaned and boxed. The cleaner specialises in wedding dress cleaning, she unpicked any mirrored beads from the bodice as the cleaning process can remove the mirroring (I researched this myself) - therefore they lose their sparkle - and then re-stitched them all back on by hand after cleaning (some were a little lose when I brought it to her, they are now all well attached and unlikely to fall off!).
The packaging and box it was put into is brilliant - same is used for antique clothing in museums.
I dropped and collected the dress myself, however she also does a collection and delivery service - costs more of course, however I do know a friend who used this was waiting for a fair while before her dress was brought back to her afterwards.
PM me if you want the contact details.
