Appropriate Compensation Question

This is long and diluted, bear with me, please. I am curious as to the opinions of others. Let us imagine one is a professional tattooer with a few years shop experience under his belt but not in any place amazing nor with any decent instruction - all self taught. Let us say this person realizes his deficiencies, was formally trained in art and knows his potential [under the right circumstances] and longs to be next to a world class tattooer with whom he hopes to become as good as some day. Let's say the seeker thinks of this as the grad school of tattooing even though he was already deficiently apprenticed and wishes to offer compensation for said privledge to the heavily experienced artist he most admires and wishes to learn by. Having come to the decision that it is an investment in himself to learn more, said indiviual is prepared to pay up to $40,000 in cash with a contract stipulating in return he is to get a "grad school equivalent" say one year being this famous tattooer's shadow and soaking up the good stuff, getting to watch the artist travel to shows and work the custom magic and leanring everything he could. Here comes the question, In your individual opinions, would a world class (read as one of the top 10 on the planet--insanely creative, technically flawless and well-respected by his pears) tattooer be offended by a contractual offer of this kind or would he likely think it was a fair exchange to take on a student he likely does not want around for a year? Let us also say the seeker is concerned he will offend the more experienced tattooer by offering too little or that other peers will somehow see this contract as negating the less experieinced tattooers actual talent?
