Small social platform for objects exchanges without money between friends (MVP)

The purpose is to create a social platform for barter (objects exchanges without money between friends). It has to be more user friendly than beautiful. 1) the user make just pictures of objects he wants to barter. 2) He do a drag and drop of pictures, eventually add descriptions. 3) He completes his account and friend list. 4) And it makes something look like a one page shop with "buy" replaced by a like button. Categories are a a bonus. 5) People located in the same area, people with URL and friends and friends of friends can seen this page. they also have a search function for all available objects for them. 6) If a friend or a friend of a friend is interested by an object: he can like it. Like for a dating site. 7) If someone have liked your object you receive the information and can check if there is an interesting item for him in the other shop. 8) If two peoples like one object of each other: "it is a match!" like in tinder. 9) They made a trade proposition with a drag and drop + messages interface. 10) People without account receiving URL can like and then have to create account to continue and they automatically sent a friend invitation to the URL owner. To develop you will have a database mysql 5.7, and ftp access (ovh) opensource solutions are very welcome to reduce development cost. This development can been seen as a test. If you do it very efficiently: more things in less time, you will be rewarded: If I found a nice developer, I will propose more to do in futur and give your contact into my startup incubator. So, if you have in mind a smart way to do it, reusing a lot of code, it will be a parameter of selection. Code have to be nicely commented. I do not give too much specifications, and I do not request a specific language to give you more freedom for being efficient. I use Skype and emails to exchange with you. English/French. Quality of exchanges are more important than doing things in time. Thank you for your attention. I hope we will work together for a longtime :o) Barthelemy
