I have gone through your requirement and I am confident that I can do it.
Please give me a chance to show my capabilities. I completed a lot of projects here & not new to Freelancer but starting again as freelancer so wants to prove myself.
Please create first milestone with minimum possible bid. If you are satisfied by my work then create another milestone with higher amount.
If you are happy with only one milestone and don't want to continue with me, give me good review.
If you are unhappy, don't pay me a single cent.
