A note regarding that form: A lot of people leave the "Budget" field empty, which causes a few problems when we find out that the price we'd require is significantly higher than the amount of money they are willing to pay. Giving us an estimate of the maximum amount of money you'd be willing to dedicate to it would be helpful in determining whether we should move forward.
Then again, leaving it empty is probably better than setting the budget at $20, and we've had a few people try to hire us for a job for that amount of money before
