a claimant performs a service for another person; and

that person makes no payment of earnings or pays less than that paid for a comparable employment in the area,

the relevant authority shall treat the claimant as possessing such earnings (if any) as is reasonable for that employment unless the claimant satisfies the authority that the means of that person are insufficient for him to pay or to pay more for the service.”
