Hi,
I am looking for a Drupal developer around the London area to develop and maintain a website.
The website is for a small training company so it will need:
** Newsletter
** Search functionality for courses
** Calendar and events (conferences,
** Teachers can apply for the courses online
** Auto-responder (email confirmation with order)
** Paypal and Google Checkout integration (to pay for courses, to buy books, etc.)
** different views for different users
** etc.
A quote with an idea of the cost would be appreciated and also hourly rate for future maintenance.
Thank you!
