Build android app and manageable back-end portal with database from scraped online stores

I need Android app (native design), that will connect to database you will also create and show products and its pricing per stores + develop scraping script to scrape 4 online stores that will update the database. App features needed: - Register/Login screen including Facebook/Twitter/Gmail logins - Setting up user profile - Age, Sex, Location, etc. - Home screen - with featured products (which admin can set in back-end admin panel) - Product search - based on name or by navigation through categories - Product page - when clicked on the product the page with price per store (those 4 that will be scraped or more if in database) and with picture and description of product will be shown. - Adding the product to the basket (with +/- option) - When in the basket, user can select an option that will split basket into lists per store so the total amount of the basket would be lowest possible when you add the lists. (if you do not understand this please ask me to explain further) - Banner/Ad features Scraping script features needed: - You will need to scrape the 4 online stores I will provide. - You will need to create initial database of it, with product picture, product category, product subcategory(s), product internal ID (our own database ID that you will define), barcode ID(s), shop IDs (where they can be taken from online stores), price per each store. - This database should be updatable via script but also manually from admin back-end. Back-end features needed: - Admin only web access. - Manageable database of products. - Data in database should be able to be edited manually through this back-end. - New online shop could be created through back-end (new price column in database) and data can be entered manually. - Management of Banners/Ads on back-end. ALL VISUALS AND DESIGN WILL BE PROVIDED, no need to work on it, I just need developer not designer. All resources (like web site, domain, hosting for back-end and database, etc) will be provided. I'm setting project budget to minimum as I have no idea how much this can cost so feel free to give your best estimate in price and time. If you have red all of this and you are applying to job, please start your application with "I'm a squirrel" so I will know you did read all :) This can be a long term project as new features would be needed and if you do a good job now, I'll probably hire you again to continue to work on the app.
