Hello
So from my understanding, you need to show the current price from the ad table? You also need a promotion price which will override the regular price and you need the layout adjusted so that it's evenly displayed. I can do this for you.
I have more than 10 years of experience with HTML, Javascript, PHP, MySQL, Linux and web development in general. While I have set a deadline of 7 days on my bid, I can start right away. I just like to give myself extra time in case any complications arise even though I don't anticipate any.
Thanks,
Danny
