Dream Daters is new to me - ah, yes, one of the 'pay us for an ad which only other victims will see' ones - but yes, there is a never-ending stream of these scams because there is a never-ending stream of gullible men who fall for them.
The only genuine 'straight male' agency I knew of closed some time last summer. I strongly suspect they had two problems: the very low level of demand and problems in advertising on places like Google because the scams can outspend them.
That leaves a) a handful of agencies which have a couple of men on their books alongside a host of women... but they are highly unlikely to be looking for more (male) staff,
b) working independently... but the level of competition is huge with around eight thousand optimistic men on a single site already,
c) partnering up with someone to work as a duo, but like the agencies most female escorts will have a steady stream of offers and most of the work will involve...
d) being sexual with men.
If you can't do (d) one way or another, the huge mismatch between supply and demand suggests you look elsewhere.
