Linked in template for Job adverts

We are a recruitment consultancy and need a template we can use to to post to our linked timeline etc to advertise for new roles. It need to be a background that we can easily add text to that that gives details of the position. The sizing of the image etc should be in line with what's required for LinkedIn posts.

Th background should be fairly plain but maybe contains a catchy image and wording relating to recruitment or someone looking for a new role (job)

We need a format that we can overlay the text as required somehow - happy for you to suggest

I have added a sample of what we do now - we created this in PowerPoint and hate it
