Blue leg hermit crabs

Hi can i rehome my two blue leg hermit crabs here? Really need help. im suddenly moving house in the next few weeks or month..i really need to rehome them. I live in greenwich SE10. I dont drive so would need them collected. Would really appreciate anyone who could take them off my hands thank u. Will give u some foods I have and other bits like water testing materials so they dont go to waste. One is missing a leg as they fought aha
