Hi,
The amount you have kept is very small considering you need an e-commerce app. Please share more details about the project. I am a Masters from Rochester Institute of Technology, USA. I have founded 2 start ups till now and have single handedly coded one complicated social app called "Hookk". It is available on play store for only people in the USA for now but you can check the website - gethookked.com. I have plenty of experience with android views and chatting engine and notifications. I am new here and trying to polish our profile with reviews and ratings. Before writing off my name for this project i request that you send me a message and i can give you demo code samples to prove my worth.
Thank you
