Hi, I had a little experience with paradox years ago, so I think it coukd be possible to understand your current source code in order to fix some issues, On the other side, I need a more detailed descrption of the requierements about the scope, limits, processes to cover, database to be used, if need to redesign something, etc. It is not responsible to calculate a timeline and a price about something without a more explicit knowledge of the project to sign a compromise.
I propose to have a more detailed chat to be more clear, in order to be sure I can accomplish it with my skills successfully.
You can see my profile and comments from my clients as a reference.
Hope to have a contact.
