Uniquely designed illustrated style images for our website

We are building our website which explains the services which we offer. We need 4 drawn/illustrated graphics which show some key services:

1. Cloud & DevOps Engineering
-See WeTransfer link for example idea. We want a shipping container scene like this but the main container should have the Kubernetes logo on it.
2. Software Development
-See WeTransfer link for example idea.. We basically want a computer which shows code being written. Ideally some Python or Java.
3. Branding & Website Development
-See WeTransfer link for example idea.. We basically want to show websites/branding on a device or number of devices.
4. 24/7 Support
-See WeTransfer link for example idea.. We basically want to show somebody taking a technical support call.

Criteria:
-The images must all be the same size
-The four images must all look co-ordinated, like they are meant to be together. Colour schemes etc...
-The images must clearly depict/show what service is being offered.
-They must be somewhat custom. I don't want stock images. They should look professional but a bit more illustrated/drawn in style than just regular photo's. Example attached.
-They must be in keeping with the site. If you are able to re-use any of our company colours throughout the images, even better.
