I have lots of Hoya, and one itty bitty pilea pep. for trade. Currently the hoyas I have for trade are carnosa compacta, chelsea, and obovata.
Also less likely but I also would trade a cutting of all of that for one pink princess cutting **worth a shot 
What kind of succulents are you looking for?
I have some stapelia I’d trade for H. obovata
I don’t have the succulent you’re looking for but if you’d like to expand your hoya collection I have a Hoya carnosa that’s over 100 years old and id love to trade for some of your hoya O
