Hi nebr384! If you are working with an academic collaborator on your proposal, it is usually more economical to obtain IRB review/approval via that institution (though it is not always a speedy process). If you do not have an academic partner or are not able to make use of their IRB, you can seek out a commercial Institutional Review Board to review your protocol. A quick web search for “commercial IRBs” will help you find lists of companies that offer these services. You’ll see that many universities have recommended commercial IRBs listed on their websites, which can help you identify reputable service providers.
