paypal integration + tpv +email bug+ admin panel

I am launching a new crowdfunding donation base platform, [login to view URL] , it is mainly working but I have some issues that need some work. I'am looking for a well capable php developer that can finish the following tasks within 1 week. -the paypal integration API: This is not the typycal paypal account where customers pay and that is....The bar that represents the % of the funded amount need to increase after someone make a payment. You will need to fill that functions: OAuthDataStore { function lookup_consumer($consumer_key) { // implement me } function lookup_token($consumer, $token_type, $token) { // implement me } function lookup_nonce($consumer, $token, $nonce, $timestamp) { // implement me } function new_request_token($consumer, $callback = null) { // return a new token attached to this consumer } function new_access_token($token, $consumer, $verifier = null) { // return a new access token attached to this consumer // for the user associated with this token if the request token // is authorized // shoul ...and probably others..and make shure that all the php work correctly by using a sandbox paypal account. -The tpv integration API...same than paypal -A stupid e-mails sending bug. (Actualy the platform send emails through the server, but when an user register or try to contact us, the platform does not send attached the content of the any email). -The admin panel right now is in Spanish. There is a file .po that contain all the text in english, and it should work only by configuring the [login to view URL] and the database...but it is not working yet...that needs to be fixed too. It is an open source code, and If you want, you can see the code, at [login to view URL] with the documentation and other stuff thanks, Jordi
