Always approach any session with the ymmv. Be it indy or agency, the decision ultimately is up to the provider, while DFK and bbbj are often possible it depends on the hygiene and cleanliness of the client, so keep that in mind if you are expecting these types of services. Some, not all but some agencies will say anything to book the call, often not even informing the provider the details of the client request, which makes for an awkward situation. Indy's are less likely to lead you astray with the services offered. Check reviews and recommendations of the providers you are interested in, where the services you are interested in are discussed or reviewed, then send them a note with your requests. The key to a successful and enjoyable session is open communication.
