Virtuemart Modifications in product page (crossed price, timer)

Dear Developer, On our partners webshop we need the following modifications: 1) At the frontpage In the frontpage In NSP GK5 module the override price is not working well now. When the partner setup an override price, for example from 9900 HUF to 8900 HUF the old price must be shown (crossed) and the new in bigger. This can be shown on the product page also (see the examples how) 2) We need to customize a the timer (live counter) on Virtuemart Product Admin Page. Every single product should have an individual timer/cunter with with the end date of the price overwritten, so each product has to have a TIMER feature (in the product admin page) where the admin can setup the promotion closing date and HOURS. (see the example) Please use the CSS codes from here (this is what I used in the examples) <div class="PricesalesPrice" style="display : block;/* text-decoration: line-through; */">Ár: <span class="PricesalesPrice" style=" color: #000; ">8.720 Ft </span><span class="PricesalesPrice" style=" text-decoration: line-through; font-size: 21px; ">10.900 Ft</span><span class="p-discount-rate" style=" display: inline-block; margin: 5px 0 0 5px; background-color: #e62e04; color: #fff; line-height: 20px; font-size: 13px; padding: 0 5px; ">20% kedvezmény</span><span style="padding-left: 45px;font-size: 12px;display: inline-block;line-height: 18px;margin-left: 5px;padding: 0 8px;border: 1px solid #ffc7a0;color: #ed5f00;border-radius: 8px;">Már csak <time datetime-epoch="1472137200" class="clock">2 napig, 00:47:05</time></span></div> 3) On the product page the amount of discount should be shown next to the price. See the example. The discunt will only show when there is an override on the price and should be counted automatically, rounded in 2 digits. The site runs: Joomla! 2.5.9 and Virtuemart 2 Important: please keep in your mind that the modifications should be optimized in mobile and tablet also
