I need to a Invoice and Billing Website similar to [url removed, login to view] - you should be very familiar with php, ajax, mysql and making the script downloadable and installable on different servers. Security is also of utmost importance.
I don't want a website that deals with all incoming business owners to set up their sub-domain in our website in exchange for monthly payment, I want the billing system to be independent so that the entire billing system can be duplicated, downloaded and integrated into other people's servers.
I want to have license control, so the usage of the downloaded billing software package from us will be controlled. for instance, if you download the software from our website, the license can only be used by a server at any point in time. Duplicate servers using the same script will malfunction. (Probably an additional linked-up script will be hidden remotely in our master server and needs to be encrypted.
I need someone trustworthy, and i can offer quite an high amount up to USD$3000.
Let me know if you have done similar things before. Billing system industry please.
If you have done a similar project in the past, please kindly list the website so that we can take a look at the quality of the web
