My bid is for 1 hour of debugging. After one hour, I will report to you the result of my investigation and if I was able to solve it. If I am unable to solve it in the hour, I will have an estimate of the amount of additional time that will be required, which you can agree to or not. If you cannot agree to the additional time, and I would require it to continue, I will return the milestone, and will accept cancellation of the project. I look forward to working with you, and patiently await any questions you have for me, thanks!
