Hello
As you know Its completely impossible to bid on this project without more information.
But from what I understand, you need to remake a old FoxPro Solution into a Filemaker 13 server solution.
From what I also can understand you would like to have some kind of PHP web interface and MYSQL interface as well?
We can create your solution but to give you a serious estimate I would need a lot more information.
Please send as much info as you can and we can go on from there.
Best regards Cez
