I have a client that want to build his Android App of Selling and buying opened for everyone who needs to sell or buy something like OLX or ebay or ecrater.com.

This App is similar to olx, but transaction/money of selling and buying is direct between the seller and buyer, the transaction money doesn't go via the App.

the procedures is like that :

* Jack want to sell his car .

* He start by creating a profile (easy mode: Real name, business name , address, email, phone number) or simply by his facebook account , But a phone number is a must.

* He receive a code by SMS on his phone, he should enter the code in the same page of profile to validate profile to confirm his identity (link his ID to a phone number).

* Email validation is also necessary.

* Now he can choose from a category of object like CARS , HOUSES , COMPUTERS, PHONES, ELECTRONICS. etc...

* Fill the obligatory fields (each category has its fields for a better look-up and sorting and searching)

* to avoid Human errors and the language barrier everything is selectable like instead of writing color : red … he can select the color from a color menu.

* upload pics (the original pics should be automatically resized to 800x600 or 1024x786 from any its original sizes ,with a very light weight and size).

* Pics are limited to the product category (e.g : for cars is 6), then if Seller is a SuperSeller then pics allowed more than 6.

*** etc... .... submit ... Post is complete, then this post automatically submitted to the [login to view URL] App (AV app) , also auto posted to [login to view URL] facebook page, if the client paid for Boosting the Post on Av App then the same should be done to boost on facebook.

* Now William (buyer) is browsing the site and he is searching or he click on the desired category or he choose from a combo for an immediate search, he should be able to sort by any field , narrow and refine the result by choosing between (eg: Year , color, price min max, state and region, etc..)

the site should get revenue from Ads of companies that wants to put their General Ads or specific product Ads, on the main page or products page or or or , banner gif, side gif, facebook ads integration , or what ever.

Secondly the site should make revenue from, examples :

Direct fixed fee, like 5$/item/


Percentage fee , like 1%/item selling price (note-A)


Monthly/Yearly subscription fee

User level should exist, Visitor, AGENT, SELLER , SUPER DEALER., each may have his discount or different rates or advantages,restrictions.

the site should make the revenue by getting money by Credit Cards (CC), paypal, Western Union, and by selling Vouchers (scratch cards), the site should generate Vouchers, and GSM PAY Paying by sim phone credits).

Dashboard and alerts for everyone, user, admin seller.....

Alerts and Notification By the App (by facebook, by sms (If paid account), by browser, by whatsapp, etc...)

Reporting and statistics for everyone.

That was the site's Ideas at a Glance!!.

The App should be very basic and EEAASSYY, Symmetrical and elegant.

NB: Many buy and sell App are there online take a look example of functionality at [login to view URL] or ebay (but simpler)

80% of this site visitors are coming from an android phone, the site should be 100% compatible with android devices, and it should fit perfectly into any screen.

i suggest , Construction & fine tuning + 3 months of support = (2000 + 1000) 3000$ - or suggest your plan and price.

Note-A : the site should have some minimum price per category (so no one can price a car 1$ to avoid commision)

Note-B : the App should detect the Phone language and apply the same language.

Note-C : The main language is french , secondly : english, Arabic.

Please don't write about yourself and skills , only write how you see this App working.
