please advise me for good developer to build suitable CRM module that matches my requirements
There are many developers here who offer custom services. It would be helpful if you could share your requirements and budget so others can understand what you’re looking for. Please note that developing a complete script will likely cost thousands of dollars.
There are many CRM scripts available on Codecanyon. Rather than developing an entire script from scratch, it would be more practical to purchase a script and hire a developer to customize it according to your specific requirements.
