Choose a day and time that actually suits you and I'll confirm it by reply, usually within a few hours. You don't chase me and I don't chase you. I'll call you on the number you leave — we'll talk about what your business needs and whether I'm the right person for it.
Skip the form entirely — if I’m free I’ll pick up, and if I’m on a job I’ll call you straight back.
Completely fine — plenty of people would rather type than phone.
