I've managed to find someone who does feet customs and she's recently started trying to do more WAM content. At the moment, she is sticking to just doing feet customs but her turn around from payment to recieving the video is rapid and the quality of her customs are great and prices are reasonable. She's happy for me to share her accounts so go get your requests in!
There are some clean ones on her OF account and she often goes live on tik tok with her feet out. If you drop her a message on her accounts I'm sure she'll be able to send you some.
