I have an excellent experience in vtiger development, customization and CRM business model. I have an experience with a huge client (international). I will provide the details of the clients when you will initiate a chat with me.
However you may go through my profile in freelancer.com and see my completed work, especially in vtigercrm. Currently I have 2 clients from Mexico and Phillipines, who are giving constant work.
I can response immediately and I will be available for chat between 10:00 to 14:00 EST.
I have English Level 1 Passed.
I have understood the outline problem from the project description and described my proposal below
1. I identified that you are expecting the main business work flow tailored into the crm. However it seems you are not sure how much vtiger is suitable
I believe most of the flows could be implemented using either vtiger standard module or custom module with vtiger web services . I can confirm when I will get detailed specification
2. I use industry standard PHP coding along with vtiger objects, so the coding standards will be optimized
3. It is feasible to follow vtiger architecture for custom development, so all future upgrades and updates from vtiger will be feasible
4.I am efficient in CRM concempts such as Marketting Automation, Sales Automation and Customer Support. This will be helpful to identify business positive ideas while developing the work flow
Looking forward your request for chat.
Thanks
