Templates for sport social graphics

Hi there. I need a creative mind to help create new templates for our sports league. One overall design can be used for all the graphics (with text changes only required) and the potential for changing backgroup imagery

Three core graphics:
Start list
Results
Blank / multi use

Size: Instagram optimised. 1080x1350

Requirements: Fixed logo for the sports league, fixed logo of two main sponsors, editable text area
Option: If an image is to be used, the ability to swap out the image (and keep a consistent design, but fresh look across the season)

Previous designs will be shared for better clarity. Generic examples provided below

Preferred process:
1. 2-3 draft ideas shared first to confirm preferred creative
2. Expansion of the agreed draft into the three required elements
3. Delivery as an AI design file that can be fully edited for continual use by me (text changes and potential imagery changes)
