Advanced Search Module for Magento-Shop

We are running a german online-shop for cigars using magento 1.4.11 with some extensions. The cigars are classified by certain custom attributes (strenght, size, format, length etc.) + the regular attributes like price. Most products are configurable products with simple products connected. We would like to have a kind of "shopping consultant"-application which is indeed only a modified search. A User should be able to insert his wishes for a cigar and then see some results. It should work as follows: Step 1: User can chose the strength of the cigar Step 2: User can chose the size/length of the cigar Step 3: User can chose the diameter-Range of the cigar Step 3: User can chose a price-range for the cigar Then the results are shown in the regular way as magento does it (search-result-site) The search-form must be designed as well. I`ll give you an example upon request. Optional request: The number of results should be shown live (ajax?) Notes: 1. You cannot work on the productive system. Either you make a backup of our system and put it on your development-server or you have to copy the live-system into a subfolder on our server. --> You always must test this on a non-productive system (ideally with our shop as have some extensions running) 2. There are some more jobs in the queue for magento. So i`m looking for someone in long-term. 3. mention "zigarre" in your bid - bids not containing this word will be ignored. 4. We are located in germany. Bidder from EU would be preferred (same timezone). I always need invoices for your work! If you cannot send me an invoice please don`t bid. This is an essential part of our contract. 5. if the budget-range for this project isn`t big enough please let me know and make your bid using PM
