Hey, I am very happy that you opened your company and I am very glad that I can help you. You can find a good stamp maker online, but it will take a while, as all of them promise a lot in the beginning but in the end, they don't give you anything. I, for example, always use this site
https://mystampready.com/en/constructor/ when I have to create a stamp because I make it in just some minutes and it doesn't require specific knowledge, so anyone can make it. I hope I helped you.
