You already reacted (Twice :-) to this project, but I guess I am now ready to discuss it with you in depth.
I'll add the documentation in the attachment. I also added a diagram with some kind of 'Datamodel/flowchart'. Hope this will clarify things a bit more.
Please let me know if you are still interested and have the time for this, so we can discuss the details.
BTW: Do you work alone? I notice you have 12 running projects. Do you think you can fit this in?
I case you're wondering: sofar I got scammed by one 'provider' and another developer was very enthousiastic but kept failing to deliver anything, or (which is far worse) communicate about it.
I guess I should just have selected you the first time! My apologies for this ;-)
Looking forward to you reply!!
