Visa fees and why is it only a multiple entry tourist L type

Hi there,
Our agent that is doing our tourist L types for PRC tells us that the fees are now over CA$ 200.00 per person. Your website does not say anything about this. Could you please let me know if this is correct. Also we need only a single entry L type but the agent tells us that only multiple entry L types for tourists are available with the Embassy.
Please clarify that we must get a multiple entry L type for as long as our passports are valid and what are the fees?
Thanks
