There is no such thing as "one reasonable price". You may value your time arbitrarily high and don't need explanation for that, and there may be someone that value money arbitrarily low and has literally random reason to hire you.
This checks as long you give your rate/price upfront. This would be a scam if you DO the work and THEN charge non-market rate/price.
