Clover, can I use You as a Reference?

I am happy to provide you with a reference, if we have had an agreeable date. Please contact me with notice (before you contact the person you'd like to give me as a reference to) to ask if I will provide you with a reference.   I ONLY provide a reference if you've seen me within the last year. I will provide up to 4 references until you see me again. Do not abuse my willingness to provide you a reference. I have the right to revoke a reference at any time for any reason.
