Joe, I’m so sorry for your loss. I can’t imagine what a horrible time this must be for you.
I’d suggest going with STH’s contacts, as they’ll likely be able to do a more professional job than me on this and do it justice.
Failing that, absolutely I’ll try and help. Lighting can often be a big problem with asks such as this, especially if the two photos are from completely different environments, so I can’t guarantee I’ll be able to do a stellar job with it, that’s all. But I will try, and if it’s no good I’ll happily try and find you someone that can help you out professionally.
