How to find a transparent EB3 visa recruiting company?

Are there any people here who had to independently search for a recruiting company to find a suitable vacancy for work in the USA on an EB3 visa? It turned out that it was not so easy to do, but still I managed to do it. At first I read many articles about how to find transparent EB-3 recruiters, here is one of them on the website eb3.work, you can check it out. I realized that you need to look for a recruiting company based on real reviews of people and whether they openly show which employers they work with and so on. You also need to pay attention so that there are no stories when candidates are forced to sign the first option right away, because I have already seen similar cases in other companies and it is very alarming. The main thing is to choose carefully, checking all the information and then everything will be fine.
