End-of-Life Pet Photographer Suggestions

Has anyone utilized a photographer for a few portraits of their animal in their final days? There are many listed for the Houston area online, but most of them have minimum product purchases associated with the base scheduling fee (one had an "average investment of 2-10k" listed on their site), and charge upwards of $500 dollars only for an at-home session. I could use some recommendations.

My dog is quite old and anxious and I would like to have just a few photos taken of us together at home as a family before he heads to his next adventure over the rainbow bridge. Thank you.
