Stamp duty payment for bonus shares

Hi folks,

background:

We are a private limited company registered in Maharashtra. We have recently issued bonus shares to existing share holders and we wish to pay stamp duty for the same. On enquiry we found that the bank is willing to do franking only for an amount upto INR 5000/- . Sticking stamps is not a viable option as the number of certificates is high. 

Question: What is the alternate option available with us to handle this situation.

AC.
