Hi, how bout the size?

Hi thanks for your qn - I was thinking something that fits the computer screen - like A4 landscape.
I'm open to what you think looks best,
thanks,
Tim

I think it would be great if you could provide a high resolution image to go on the flyer if you think its okei for you. Adding an image (maybe a class room photo with a teacher teaching students) will probably make it very attractive for a design like this.

Also do let me know if you don't want an image on this flyer.

Thank you.
