Researcher needed to find artists producing erotic art (Adult)

I have just launched a site selling erotic art and I need to find artists. I want someone who can find artists and produce a list of artists and artworks for me to look at. I'm looking for a specific type of art - that may offend some so obviously don't apply if kinky erotica offends you. I'm looking for artists who produce art of submissive/slave males and dominant females. Ideally I'm looking for a native English speaker with social media research skills. For the right person there will be repeat work. You must understand that I'm looking for a number of quality links rather than a mass of spam. I'm not looking for thousands of twitter followers :) I'm looking for around thirty artist leads and expecting to pay around 50$.
