pgRouting: A Practical Guide
Learn how to build applications with road routing and vehicle resource management considerations using pgRouting, PostGIS, and PostgreSQL.
On-site work rates will be negotiated on a case by case basis, but will generally fall in the $150-$200/hr range plus travel expenses.
To get established as a customer we require prepayment (only off-site / on-site requires negotiation) before beginning work of $150/hr for 4 hours or less, $120/hr for 5 - 9 hrs or $96/hr for 10 hrs or more. Once an established customer, you will be billed monthly at the below rates.
Rates listed below are for work done on our premises (off-site work).
Project-Based work is pre-billed 20% of the estimated cost before work can begin with a minimum 10-hour pre-payment requirement for new customers. Project work is any work deemed to require 10 or more hours worth of work.
