If you have no one to help you negotiate the price maybe ask if he can give you a little off for repairs. As for asking family to help you, be careful, you dont want them to think you owe them something...it's better to pay ppl you dont know then to get free favors from family...believe me...its the whole strings attached thing, and holding it over your head you dont want. Or even worse waiting on them to "finish"..lol....get copies of all papers you sign!..and receipts!! take pictures as well...(I have seen too much Judge Judy)
