Tillett paintings on silk/fabric

I have several paintings by Tillett that "came with the house". There's one with Water Island topographical map and then the others are ........I'm not coming up with the correct terminology for the artistic methodology/style so please forgive me in advance........some abstract marine life scenes and also one with like green philodenderum-type leaves with blue parrot in the center. Anyway, over the years they've gotten some water stains and for sure they need a cleaning. Is there any place on STT someone could recommend? I'd like someone that is skilled and would be careful to preserve/maintain the quality - not harm the image and the fabric - so appreciate recommendation for a shop that you've had good experience. Thanks!
