Creating a mobile app for both google playstore and Apple appstore similar

Hi all, For this project i will require the freelancer to do up a mobile application similar to this app - [login to view URL] but it is mainly for GOLF related products. Please download the app from your mobile phone as an example of the whole project It will be a mobile platform for user to sign up as a member via email address or their facebook account, Thus upon signing up as a member they will be able to post their pictures of the products that they wish to sell together with the description and pricing. And users will be able to make an offer accordingly to the products 1) Browse tab - Main Page with different Golf brands And once member tab into different gold brands will be pictures and description posted by members, can click into the pictures for clearer look, Maybe we can add on another tab for golf country clubs. (For us to target clubs to put their membership with us to attract more people. - Search filters must also be able to filter via pricing of the golf sets accordingly 2) Activity tab - Able to browse you recent activity, exp : who have like your items and who have made an offer etc 3) Me tab- Your own profile with your own listings I have a few more projects on hand thus you can expect more jobs from me if you are able to fit my job criteria with good service. Most importantly i will require the first mock up of the app within 1 week and the whole project to be completed by 3 weeks (NEGO)
