Need Magento customization work

Hi, I need some customization done for my Magento based store. A Little about site: The site sell Wine and Spirits. The site is based on magento version 1.7.0.2 with ULTIMO theme installed. The things that are needed are: 1. Option to set up FREE Local Deliver in Selected 5 to 7 states that i will inform you - so any order that is from those 5 to 7 states will get to see the option of Free Delivery. 2. UPS and FEDEX Delivery option - we do not ship to Certain States so if order comes from those states then an alert has to come in showing that "Currently we do not Deliver to your state" - or something like this. 3. Option for a person to Pick up his Order "In Store" -------------------------------- 4. Multiple Search Filter to be placed on Home page, Catalog page, Product page. We need checkbox in the filter options and a person should be able to select multiple search fields and then press "Apply" to see the results. The MAIN Search Fields will be Wine, Spirit, Price, (maybe 1 or 2 more main fields will come in). Wine Category will have about 8 fields to choose from, Spirit Category will have about 17 fields to choose from. Please note - Every option with Checkbox should be shown even if there is No item in that option. I MAY ask you to change the position of the search fields placement. 5. We need to give 15% Discount to customers who buy 12 bottles (a case) - in any combination of items either from wine or spirit. 6. We need to give 5% Discount to customers from NY State. 7. In case if order comes from NY state and the person buys 12 bottles then he get 15% + 5% Discount. (I need the ability to change the discount percentage) -------------------------------- 8. Manage Inventory - we need ability to EXPORT the items with their inventory level along with Names and UPC code, then we will edit the inventory manually and again IMPORT the csv file back into the Magento. ------------------------------ You should be able to give us few revisions in case if needed, Please give us your final price for All of the above work. I will release this order by this week end and expect to get the results back in 2 to 3 days time Everything that you do to achieve the above results should be well documented and conveyed to us. Follow Magento practices. Please tell me your Hourly Rate also. warm regards
