Why do quoted prices vary so widely?
Because scope varies widely. A ninety-minute group workshop and a four-month programme with weekly one-to-one hours are different products. Compare contact hours, deliverables and who actually does the work before comparing numbers.
Is a higher price a signal of better outcomes?
Not on its own. Price signals scope and the seniority of the person delivering it. Outcomes are signalled by verifiable named results with a stated sample size, which is a separate question you should ask directly.
What should be in writing before I pay?
Total fee including taxes, exactly what is included and excluded, number and length of sessions, who delivers them, turnaround times, the refund or pause policy, and whether anything renews. Verbal scope is where disputes start.
How do I avoid paying twice for the same switch?
Decide which band matches your actual gap before buying. Paying per-session fees repeatedly for scattered problems usually costs more than one scoped engagement, and paying for a programme when you needed one resume review is the same mistake in reverse.
