Cover need for four English classes a month

I teach English classes for adults and teens at an Academy near metro Oporto, and due to my own studies I need regular cover of four classes a month, two on a Friday and two on the following Monday. Pay is 14.50 euros per hour, with six hours of teaching in total.

Classes are on Fridays 16:00-20:00 and Mondays 16:30-18:30.

I need cover until June, but if you're only sure about a few months let me know.

The first three dates are as follows:

September 28 / October 1
October 26 / October 29
November 23 / November 26

Looking forward to hearing from you
Sam
