Looking for a paypal expert for a PHP integration


I am currently on a project wich need to use some advance options of the Paypal API.


The project is to have a deal with multiple prices, depending the number of buyer. For example :


buyers < 5 : no transactions

buyers >= 5 : 20$ < ACTUAL PRICE

buyers >= 10 : 10$

buyers >= 50 : 5$


##For example :

> A person take the deal, the price is actually 20$.

> The person go to paypal and preapprove the 20$ amount

> Some days later (1 day to 1 month max. ), the deal is finish.

> On finishing the deal price is 5$, so the person have to pay only $5


We don't want any refund system, you have to use preapprouved payment.

#Deal end

The money we take should not go to our paypal account, but to another business account. So we transfert all the funds to our paypal account and then chained the payments to a unique another Paypal account (we have only the email account). All the transfert taxes is for the destination account.


> Good knowledge in PHP5 (OOP)

> Good experience in Paypal Adaptative payments (Chained and pre-approuved payment)

#What you have

> HTML form when the user accept the deal (provide : seller_id, deal_id, actual_price, deal_description, deal_title)

> HTML form when we end the deal (provide : array(seller_id), deal_id, final_price, destination_email)

#What you have to do

> The php classes and a working example in paypal sandbox.

> Design SQL table to save transactions and permit pre-approuved payment

!! PLEASE !!
1) Read description
2) Provide me a total price for this project and an estimated time
3) Told me about your paypal experience (examples ?)
