How big was the original HDD?
What should I say from a business standpoint ;(
That's a tough call man, I mean from one standpoint, you stand to gain $100 if everything goes well, but if you don't think you're capable of providing a sucessful completion of what the customer wants, you could get a bad rep.
If a mechanic didn't have the know-how to fix a fuel-system failure, would you rather him be upfront or jerk you around?
Just some things to consider. Let us know how it turns out.
PS : I didn't mean that with a negative connotation, just could not think of another way to say it.
