Voluntary: Mathematics - Career Orientation - Job Search

Hello/ Buenas,
Although I have a busy schedule, but I am willing to spare  1 - 2 hours per week for anyone in Madrid that needs support in understanding Mathematics or needs some career orientation or some advice in Job search.
I won't charge for my services ????, but if anyone gives voluntarily, I won't deny either????. Presencial I can support only within 30 minutes of travel time in public transport from Madrid center. Kindly contact only if you are looking seriously for the above mentioned services for yourself and/or your Family/ friends. Have a nice day.
P.S. puedo hablar en español también.
