Ok guys need advice!

We want to get married and make that commitment to eachother and share the same name as a family before we quit renting and get a mortgage. We already live together but are ttc and want to get married so bad. Funds are low as we are saving for our future... But for now we're thinking something cheap? Anyone know if its possible to have a cheap wedding? What about a courthouse? We plan to put off a big ceremony for 5 years and then do it big with the kid(s) involved. I believe marriage is about the vows, love and comitment, but then it would be lovely to have our little one part of it to create memories that will last a lifetime. Has anyone got any advice? 😊
