Graphic design to be used on social media

Hi, we need a graphic to be developed since we reached 1000 users on our platform (www.aircnc.it). The words would be " 1000 aziende italiane hanno scelto aircnc. E tu?"
We want it to be a celebrating and happy message but with an industrial and professional mood. No champagne bottles or similar. We would like a minimum of 2 graphics to choose from. The image will be posted on facebook, linkedin and instagram. I attach some graphics to give you the idea of our brand.
The work should be delivered within the 5th of december.
Thank you.
Elena
