Start with what is getting in the way.
You do not need a specification, a technology stack or a carefully polished brief. An imperfect explanation is enough.
A useful starting point

It is helpful to include a little about your organisation and any constraints or timescales you already know about—but there is no need to solve the technical part before getting in touch.
Email first
Email is the simplest way to make an initial enquiry.
