Customise SiteMile Wordpress project theme template.

Customise SiteMile Wordpress project theme template. I was looking at several options for wordpress Auction themes on the web and found yours to be particularly close to what i am about to achieve. Our family runs a local wine distribution company and we often require several quotes from our main suppliers for an order. We want to link our regular customers (buyer) to our supplier vendors (seller) directly using a reverse bidding method to reduce our administrative footprints. (If you are lost at this moment u can think uShip.) I also need a dispute centre & customer loyalty module as well. I require turnkey solutions & customisation. My requirements after some brief analysis of the SiteMile product includes the following functionalities, which i'm currently looking for. 1) Reverse Auction where buyer and seller roles are inverse. Our customers are Buyers and our vendors are sellers who undercuts bids. 2) 2 user profiles excluding admin, Buyer profiles enables them to create bids or RFQ. Seller profiles enables them to place bids and undercuts (or direct pricing proposal) 3) Buyer can choose to award the bid to top 3 most attractive pricing or can choose to go for another other bids with higher pricing. 4) Country based searches which accommodates to some of our vendors from Australia or Asia Pacific. (instead of zipcode based) 5) Proxy bidding for sellers 6) Dispute centre (like a service desk with ticket options or simlar dispute modules plugin) 7) Changeable child theme to fit our image. 8) Buyer pays full amount our PayPal according to bid awarded. 9) Email notifications to send delivery orders. 10) Disabling but not removing certain functions like Percentage fee auction, monetisation tools (unfamiliar), private messages. I am looking for honest and experienced people who are good in Wordpress (using SiteMile) project management and can give me proper milestones in development phases.
