Researcher to find case study

I am a journalist and I need to find a couple who have taken up tango thinking it would be good for their relationship but have found the demands, challenges etc. have in fact created strains and threatened to wreck the relationship. Could be because one partner progresses faster than other, is more desired by other dance partners, becomes infatuated with someone through tango etc. But it must be quite a dramatic tale . They would need to be interviewed and photographed.I could pay the couple £75 between them.
