There are lots of photographers out there. Any one of them can take your photo.
But who's going to do the best job?
It's the one that you have the best relationship with. You trust them.
Not everyone has a photographer in their friendship group, but if you are networking enough, you know someone, or someone in your network does. And that is the best place to start.
Google can find photographers, but it won't take personality into account. It won't take your level of discomfort into account. A refined search may narrow possibilities, but if you want to love your images, then you need to work with someone who already knows you. Who can make you feel comfortable during awkward poses, who will make the process fun. Where the shoot feels more like a collaboration than a transaction.
Bear in mind that the photographer you know may specialise in something different to what you want - but chances are they can make a recommendation for you. Most photographers know other photographers. Start with who you already know. Someone may even be starting out and looking for a portfolio project.
It may mean a bit of extra effort and time spent on the process, but if the imagery requirement isn't urgent, then it's worth it to get not only the results you want, but results you love.
