I run the injured cyclist program at my clinic, and I do temporary orthotics for no extra charge. (they are included in your insurance payment for the PT session). A good PT should be able to post a pair of insoles for you, AND give you exercises to help correct the problem, AND show you how to trim down the posting until you are strong enough that you only need the neutral footbed.
A good PT should also be very aware of the needs of a cyclist's forefoot, and absolutely should put you on your bike in the clinic and assess your body function ON YOUR OWN BIKE.
ETA: of course, if you have a true deformity the PT will recognize that and send you on to a licensed Orthotist, which likely will be covered by your insurance.
