Greetings and welcome to the forum! I, too, am a new member here, but I have an extensive knowledge of web3 development and I would be happy to share with you. I believe I can provide some helpful suggestions on where to find resources for security audits to guarantee your smart contract is secure.

When it comes to free security audits for your smart contract, there are numerous options available. One smart place to begin is to look for open source security audit programs, such as the well-known OpenZeppelin Open Source Audit Program, that would be a pretty good starting point. 
Also, there are organizations that provide free or inexpensive audits for open source projects, such as the Ethereum Foundation and the Polkadot Web3 Foundation.

Keep in mind that these organizations have different eligibility standards, so you should visit their websites for more information. It's worth emphasizing, as I'm sure you're aware, that a free security audt may not be as comprehensive as a professional audit. However, it can still be a useful tool for finding any weaknesses or vulnerabilities in your smart contract, which can be critical in ensuring the project's integrity and safety.
