Hi,
First of all, welcome to this forum, we hope to provide you with overwhelming support.
Secondly, this goes for everyone posting, lets not make remarks on each other's English. I can easily pick out some posts in both Dutch and English and find some mistakes in it.
The most important thing is that we can comprehend each other. As English isn't often used on this forum nor well spoken we tend to ignore those mistakes, or at least, I do.
Now, onto the matter itself:
It appears, based on the recent posts, that the source does not posses an admin panel. What you could do is either create it yourself or hire someone for it, as mentioned before.
But what you also could do is take out the admin panel of a different source and use it for yours. Of course, adjustments are required.
Yours faithfully,
Tim
