Illustrations / sketches for blog posts

Hi, we are looking for someone who can create simple sketches for us to illustrate a story we are creating in the context of our brand. The next parts of the story can be found here: https://slickhaven.com/blog/ As you can see at the moment there is not much to illustrate it with :)

We were thinking about permanent cooperation - about 3 sketches a month (or for example once in a while a package of 10 illustrations). To put it simply - we are looking for a reasonably inexpensive option since these would be sketches only to be used for these blog posts.

In form, they could be simplified sketches - something like this: https://1drv.ms/u/s!Avs0T0WmxhALhIwIaFrut5O5CQx-1w?e=FqQ6IA, only on a yellowed sheet of paper like this ->https://1drv.ms/u/s!Avs0T0WmxhALhIwJ3_K2X0d5B2kA-Q?e=hOxf1t :). The purpose is to simply illustrate in a simple way what is happening in a particular episode of a story.

E.g. for the first story (https://slickhaven.com/opowiadanie-1-cesarski-botanik/), it could be walls, a gate, 2 characters behind the gate.

In order for the cooperation to be fast, efficient, and not very time-consuming, after the first illustration is done we wouldn't need any options for corrections or changes in the next ones.

I would be grateful for the price of a single illustration on the assumption of permanent cooperation/packages and also for showing me your works - preferably in some similar style.

Thanks!
