I need a mobile app developed

I have a client who is looking to build a mobile application. It's a dating application and you can find the high intended workflow here: https://protect-eu.mimecast.com/s/3qwLBC3WkN7uE?domain=app.box.com What I need is a mobile developer who has a PROVEN TRACK record. Please post your best examples of work (android or iPhone) in your response. (Any applications that ask me to look at their profile for portfolio as opposed to pasting examples in their response, will be automatically rejected) I need a dev partner who is NOT part of a large agency and who I can deal directly with the developer. (any applicants who are applying on behalf of a large agency will be automatically rejected). Right now what I need is a developer who is able to provide an ESTIMATE based on the link I pasted above (i.e. the workflow)... and come up with a proposal. I need a dev partner who is able to work and communicate with me using the following tools: - Slack - Trello - Skype (any one who replies to this and does not use the above tools will be automatically rejected). I am not opposed to working with partners outside of the UK, but I do require that the dev partner speaks good english... purely because otherwise communication will become extremely difficult. (Any applicants whose english is not good- unfortunately your application will be automatically rejected)
