Development of a community platform - Drupal

Development of a community platform - Drupal
I am looking for a provider to proceed with the construction of a community platform, integrating a payment solution online custom.

The requirements are as follows:
* A survey module improved;
* A forum;
* A news feed;
* Payment solution;
* A jQuery slideshow;
* A few pages;
* The construction of an ad-hoc theme.

The desired service is a developer with whom I will wish to work in the long term for specific missions.

Drupal seems entirely appropriate for this project and the service will always be a "Drupalien".

A detailed specification is being prepared: this ad is a contact for a quote.
