Knowledge exchange? - Illustrator needed

Hi guys! Newbie here! I am a freelance social media manager and working along all digital platforms I found myself with some difficulties with Illustrator but I don't have knowledge enough. I would like to know different alternatives I can start with. I checked some courses close to my home (Mac Beth centre in Hammersmith, London i.e.) but they don't do it anymore. I think that maybe is better if I do self-learning. What do you think guys? I was wondering as well in doing some knowledge exchange with someone interested in promoting themselves through social media as I know quite well in that area. Or maybe someone who wants to learn Spanish as I am from Madrid. Let me know please ;D.
