Dear Sir or Madame,
We are a small German based company primarily specializing in vTiger custom development, maintenance and hosting.
During the last 5 years we could gather deep knowledge and understanding of the vTiger architecture and the underlying technologies.
Also, we already created several industry solutions based on vTiger for our clients.
Thus, core development as requested by you is only a small part of our vast vTiger expertise.
Kind Regards
