Is the casting couch a must for doing semi-porn Indian films?

Of course!!

Any producer who wants to make such films have to experience the magic before he starts the shoot. However finding such girls is not so difficult.

There are zillions of co-ordinators who keep advertising for ‘compro’ projects and keep such girls handy. Once they know what their rates are, they get them connected to the producer. The co-ordinator in most cases lets go his commission as a barter deal for a night-out with the girl.
