Hi,
We have done a couple of projects for shipping companies including management of shipped consignments, arrival and departure of ships at different ports and managing airway bills, agencies, brokers etc.
We have experienced engineers worked on Zend 1.0 framework and working towards getting certifications for Zend 2.0.
As per my experience, I can say even you have designs and basic project ready on joomla, this project can not be completed with in US$1500 budget and in time.
Our rates are US$15/Hr for Sr. Developer and US$25/Hr for PM and PL. I can only give you an estimate after reviewing details of project and we can negotiate.
References in Shipping Industries for whom we have completed projects can be provided on request.
If you are interested, please get back to us.
Thank You,
Warm Regards,
Team AthenaResearch
