Hi Chris - my name is Michela and I'm new here on Freelancer, but I have plenty of experience in creating logo designs. I would love to work with you on this project - if you want to take a look at my portfolio (https://www.freelancer.co.uk/u/MDesigns20), you will see that I recently designed a logo for a children swimming club, so it would be great to work on a similar project.
I think your unique selling point of offering lessons in Swedish and English is a great start for the logo concept and, as you mentioned, including the nationality flags could be an immediate visual cue for your target audience. I would love to carry this concept further and I already have a few ideas of how it could work with the letters of your company name.
I can provide you with the first concepts by tomorrow and then I will offer you unlimited revisions, until we reach a solution that you're 100% satisfied with. Costumer satisfaction is truly at the heart of my work ethos and I will ensure we communicate clearly throughout the process, so that we're always on the same page.
I always work in vector graphics, which are scalable without any loss of quality, so rest assured that the design will look great both in large and small scale. In addition, I will provide you with copies of the design both in CMYK, for print and RGB for screen - this will ensure that the colours are consistent both in real-life and on screen.
Feel free to contact me if you have any more questions.
Best wishes,
Michela
