Dear Sir,
Do you mean you need 7 icons?
Or need graphic design to descript your business.
Could you please provide some reference images?

Thank you.

Yes, I'd refer one simple illustration per department, so 7 illustrations in total.

Hi, I've submitted a design please kindly provide me feedback.
(Design #26488120)
in case it's not perfect 'eliminate ' without ratings.
Thanks

Dear sir, I have made 1 Illustration as per the requirement, kindly check and let me know your feedback's so I can create the rest illustrations,
Thank you

The test one looks great, so feel free to move forward with the rest of the illustrations in this same style. Thank you!

I have submitted 2 designs. Please provide a feedback and I will continue the work :)
