Specialist Programmer Opencart

Good afternoon. The site on opencart, there are two problems:
1) to Configure the filter. The challenge in the trail. We have the range consists of wine, in which there are different varieties of grapes.
You need to make in the column filter the grapes were all varieties of our Vinogradov and clicking on one of them, appeared all wines containing the grape.
2) Add the category of "Manufacturers" the Problem is that when you click the "producers" opened a page with a list of all our suppliers. It is better to draw not just text, as for example banners with their logo. Then by clicking on one of these banners need to have a catalogue of all production of the supplier ( even from different product groups )

Very much I ask to respond only to those who will be able to implement it. Write your budget proposal. Thank you!
