Mobile development

I need a responsive website. I would like it designed and built. I need a cheap smart watch which would be used to listen to music, listen to fm Radio, used as a watch, recieve calls through Bluetooth connectivity with smart phone, recieve messages and emails, view pictures using Bluetooth connectivity to smart phone. There should be atleast 8gb worth of memory. Should have built in speakers. There should be a D logo on the back of every watch. Should NOT be a removable back, Should come in a plane white box which has the D logo and says hillon watch which makes it look like dhillon. In the box there should be a charging cable, 110/220 adapter, headphones, and aux cable. All this shouldn't be hard to find because there are thousands of smart watches on [login to view URL] all it takes is somebody to do some research. Now for the app development. It's really simple. When the user downloads the app from the Google play store or app store onto their phone. It should first ask to subscribe for $4.99. This app should basically be to transfer music to the watch using Bluetooth.  When subscribed there should be 3 tabs.  1. On this page you should see; Connect to smart watch. Watch storage (this should show all the songs already installed and should ask if the user would like to delete any songs) and how many songs they can download until the entire memory is full.  2. Current downloads (if the app is downloading or sending content to your watch)  3. Songs (the place where they can click and download all the songs listed and transfer them to smart watch using Bluetooth connectivity with smart watch).  I have all the songs on a Hardrive and wouldn't mind transferring them to a cloud or server but there must be an easy way to upload constantly for latest songs straight to everybody's app ready to download and transfer to watch. For me to place my first order of 100 pieces I first need a video of an unboxing of the Watch and transferring the songs to the watch from the phone app. After I see the video I will pay you $200 for shipping. After we've tested the prototype we will then pay for the next 100 pieces. ($20/piece) Please give me a good value for the app and manufacturing of the smart watch because I will be purchasing 100 pieces for first order then expecting to order 200 or more pieces per month.
