Anniversary/wedding Celebration after Elopement

Hi y’all! My husband and I got married in March of this year, we eloped at a courthouse due to his upcoming deployment and other military-related reasons. I’ve been trying to plan a reception with our friends and family however his multiple deployments within the next year have made that impossible. We’ve finally settled on March 2020 on our two year anniversary. All our family and friends know we are already married, there’s no lying or deception. We just simply want to celebrate our marriage with our loved ones. So I’m asking how to technically word our invitations and everything that will go along with the vow renewal/marital celebration. We are planning on having a ceremony where we recite our own vows (since we didn’t do this at the courthouse) and then a reception with dinner and dancing! I’m just looking for some advice/etiquette on how to go about this since it’s very non traditional.

Thanks in advance!
