Word Search Puzzles - Android

Hi, I am looking for an android developer to write a word search puzzles game similar to the game below: Reference app: [login to view URL] All bidders MUST download and make sure you're fully understanding the functions of the reference app before discussing with me. Also, this project MUST be completed in between 2-3 weeks. So, please don't bid if you cannot meet this requirement. The product of this project MUST: - Include all functions of that reference app (but with different word sets that we can discuss later) - Design graphics, sounds and codes - Works well in Android - Flexible to add more word sets - Support in-app-purchase for more word sets - Add specific SDKs for banner ads and nag screens ads - Add specific SDK to analyze user activities - Sharing results to facebook There will be two versions. One is Free with ads and other will be paid without ads. Budget is negotiable.
