To approach this situation, you have to define an agreement with the janitor. The agreement should be "send me the chemistry master and I will pay you after I have written the exam to confirm it is actually a chemistry master or pay you 1/10 of your amount if it is not, to compensate your efforts". After sending this agreement, you should focused on your studies like you're not expecting a positive response from him.
Negotiation should not be involved in the agreement, as it will waste your time of studies.
