PHP.mySQL.Drupal

We are in need of a serious, reliable part time consultant to over view the current development of a drupal site. The site is currently under development and we need to look into solutions in modifying modules that don’t operate exactly to our requirements. It is a job/networking site with a lot of features that would need module modifications. There shouldn’t be much development needed (although there maybe some) but more driving, supervising, consulting and decision making tasks.
