Build an android app

want an android app like expense manager. but it's not much complicated. simple for my personal use. requirements: must meet the play store requirements. insert my admob id too. condition: no mile stone wont be released until i check the app 1st i will publish in store. if everything goes well i will pay you full payment at once here, then after you should give the source code. it's very imp for me for future updates. if this condition is ok, then only BID. type: willing as first word then add your proposal.
