Only Expert Unity3D+AR+Magento mixed experienced developer

Greeting freelancers. The more details will be shared and be discussed only to preferred freelancer. Developer for my business, have to be familiar to handle my existing Unity3D+AR App project and Magento. Meanwhile I need someone who can do fast work, with low rating. Only after completed, all payments will be possible. budget is a little low, and timeline is so tight. ***** my fixed price: 200 US$ ***** time-frame: 10 working days, including weekend. ***** it will be possible for me to chat only with someone who looked into and understood my target thoroughly. ***** after considered many times, put your bids. not spam. no auto-bidding. I'd like to mention this again and again I prefer only strict and exact developer. Thanks.
