Android Application Development

I need a simple application created for my business. It should be working with internet connection from any Android mobile phone. It is about products with reduced prices. 1)The customer should be able to choose between several categories example: - Technology - Apparel - Games - Toys - Health - Gifts - Everything Else - All of the above 2) When there is internet connection - the app would extract data from a web-site / or another online source that will be maintained by me - preferably Wordpress based web site, created fully by my side. 3) When a new article is written in the selected category the app automatically downloads the content (text + images) 4) The image of the product would contain link - so when the customers clicks on it a mobile browser should be triggered and redirected to the link 5)The app should have options for auto articles update and manual update. That is it.
