تطوير سكربت Symfony PHP

السلام عليكم ورحمة الله وبركاته

قمت بشراء سكربت php للفواتير والمحاسبة ويمكن الاطلاع على السكربت ومميزات ونسخة تجريبية : http://codecanyon.net/ite...

ولدي تعديلات بسيطة وابحث عن مبرمج محترف اعتمد عليه في التطوير, وادناه التعديلات :

Contacts:

Possibility to search by mobile number and custom fields was added.

Possibility sorting by any custom fields was added.

Possibility of exporting the results of the search result report.

Custom Fields:

Add new type of fields (Attachments).

Services and Products:

Ability to add cost of service and product.

Invoices:

Invoices report .

Costs and profits of products and services report.

Permissions:

I need to create users or groups with custom permissions. Ex: Salesperson can only add and edit invoice.
