In Central PA, we charge $250 for the camera itself and an extra $100 to use the locator to find the location of the problem, if needed. We charge $30 to remove the toilet. Toilets are easy to remove, but we charge an 'insurance' for removal since toilets sometimes break, and we have to replace them free of charge.
Beware of people offering 'free' camera service. As Rob mentioned in another post, cameras are very expensive, and companies have to pay for them somehow. It is easy to 'find' a problem when you use a camera. The homeowner won't know how serious it actually is, and the company can then upsell you on a repair job costing several thousands of dollars.
The rates listed here look reasonable.
