We understand your problem.
We will place the new slider within a day, we need one more day to test the bandwidth its consuming(performance testing) and then you are done with your slider.
We will not bother you about the money as you have already mentioned, its not a problem at all but yes we would like an good review if you like our work.
Hope to hear from you soon.
Waiting for your reply.
Thanks & Regards
