I need a logo

Information for the business: an online course on instructional design
Industry: Education
Type of logo: Pictorial mark
Ideas for the visual style: simple lines and shapes
Where the design will be used: web
Extra notes: I need a logo for an open online course that I teach called the ABCs of Instructional Design ( https://www.udemy.com/the-abcs-of-instructional-design/). I would like the letters ABC and ID to somehow be incorporated in the logo.
I am an instructional designer, which means I design online courses, instructional videos, presentations, etc. In the course, I am teaching other instructors how to develop and implement an online course. The current image is very simple, ABC blocks. I like the blocks because they indicate 'building blocks,' but I am open to suggestions. I need the new logo to creatively include the letters ABC and ID. I'll be using the image for both print, and web, so your professional opinion about the best file type(s) and highest resolution would be appreciated.
Dimensions: 2048 X 1152 pixels
File format: native illustrator file and recommended file type(s)
