Where to order an audit of a company's smart contract

There are problems in the operation of my company's smart contract, so I decided to order an audit. What specialists can perform such work quickly and professionally?

I believe that smart contract audits should be conducted regularly to identify any vulnerabilities promptly. It is best to entrust such work to specialists who are well versed in blockchain technologies, for example, a company like this https://pharosproduction.com/smart-contract-audit I have already cooperated with them and was satisfied with the quality of services.
