Any basic image editing software is capable of achieving this.
Create a new file with a large canvas, import all the screenshots of your items and save it as an image file.
Optionally add background layer and prices with the text tool.
Depending on which software you have available you can find tutorials on YouTube if needed.
Gimp2.0 is a good free option if you don't have Photoshop for example.

If you need any help with this feel free to reach out to me.

In case you would prefer to hire someone to do this you can also create a topic in the graphic request section:

Make sure to give detailed information on what you are looking for and what your budget for the request is.
