my wife and i (wife, Singaporean and I, PR) want to register a company.After some discussion we decided to add both my parent-in laws (they are on long- term social visit pass)to the owner/shareholder of the company(just the simple 25% share each person). On the ACRA website i found rules below

The *person carrying out the business is required to engage the services of a professional firm (e.g. lawyers, accountants, chartered secretaries) or a service bureau (e.g. DP Bureau) to submit the online application on his behalf if any of the partners does not have SingPass. Only an individual with SingPass can proceed to submit any online transactions or perform the required endorsements via BizFile (ACRA’s online filing system). They will need to log in to BizFile using their identification number (NRIC or FIN no.) and SingPass.

For my case, as my parent-in laws do not have singpass, i have to engage those professional firms? if yes, could you help to suggest to choose which one of those professional firms is more cost effective. As shareholders are all direct immediate,I want to do it as simple as possible just meet the ACRA requirement and register the company. thank you in advance
