Couple's branding

When we get married, we are changing our names and want to create a personal logo / emblem / image that we will use on some of the wedding stationary, but also something we will use for the next 60 years...

We are using Gemini (because everything starts with AI these days...) to give us ideas and help us choose what we want. Once we select a core design, we would like a professional designer to create the final set of stock files we can use in future (e.g on letterheads and anything else we think of)

I have used the "per hour" budget type because I honestly have no idea what is a fair expectation for hourly rate or likely number of hours. I am very open to recommendations and what we get for it.

Thank you
