Code Editing + Lazy Loading + Hit Counter

Hi this is what I need, i.e rename php links, add lazy loading technique on part of the website, I also need a hit counter. Site response to be made faster... No more than 4/5 hours of work. I will not pay a deposit up until the work is done and I release funds (you are free to change cpanel password) the reason being is that I have deposited money in the past and I have been let down by developers and they have either never responded or they have left the work 50% done. I need the work done today please, so do not bid if you cannot fullfill, I can also pay today, Look forward to your bids, Many thanks.
