Hi,
I am a Singapore based FileMaker developer (close to Malaysia, being your requirement).
I may be new to this platform (Freelancer.com), but I am an expert FileMaker developer. I have developed applications on FileMaker, FileMaker Go and FileMaker Web Direct for various clients. My latest client in California is an events company where I developed a system involving cost (of materials) and selling price to customers. A module of the system creates job orders and another module manages the graphics for the clients' events. Lastly, I also developed for them a CRM to unify all the data and track clients and their orders. These are similar applications to your requirements. I have the complete skill set to understand business and translate that into useful software implementations.
You can see screenshots of my work on my profile for your consideration.
Thank you and look forward to having the opportunity to develop and adapt your system to your business.
Stefano
