I went through something similar last year and my main takeaway was not to call the first name that shows up in search results. What mattered more was whether the practice areas were stated clearly, construction accidents, commercial auto, pedestrian cases and so on, because a firm that handles everything rarely handles anything well. Referral services can be reasonable if they explain how the matching works and what the fee arrangement actually is, so if you want to see how one of them presents it, https://michaelbrook.com/en is one example worth reading through before you compare it with others. I would still check the attorney's own bar record separately and ask directly about costs, since no upfront cost usually means a contingency percentage that varies. Take your time and compare a few options rather than deciding under pressure.
