Logo for English as a formal language training business

Hi,

I need to redesign the logo for my business. I work mostly as a Business English Trainer and I also teach working skills for non native speakers, as well as general English and exam prep to adults and companies. I have a logo at the moment which at first glance can look like a porn site because I wanted a play on words with my company name, Adult English Only. Unsurprisingly, I scare some people off and corporate companies won´t approach me directly. I need something that is in line with the things I already have, but more appropriate and funky. I have an idea of what I want to play with, and can show you my website (homemade due to budget reasons), Instagram etc so you can see the type of image I am going for. I will gladly share my current logo and other stuff with you if you want to have more info, just let me know. Thanks.
