Hello,
Thanks to provide me opportunity to bid on this project. I have read task very carefully. I think that I have understand your requirement. I have 10+ year experience in PHP, MYSQL , source code customization in many open source like osCommerce, wordpress, opencart, magento, smarty etc. and many more customized projects, special experience to develop real estate search portal & multiple sites manager for agents.
As I understand your requirement, it is Customer Relationship Management CRM and few points related to it are as follows. There are 3 main parts for task. 1. Leads- It is a process on which customer and admin are start conversation? Leads will be set different status accordingly discussion(call) time to time, 2. Deals- Admin user goals is to convert leads to deal, means lead will be saved as customer or account, 3. Reports- About deals, lost deals, these are related to follow up leads which are not converted to deals and also related to deals which had expired or about to expire (60 days before)? We should discuss more about it.
Thanks & Regards
