Developer for improvement in K2 is needed !!!

we requiere a Developer to improve K2, We are interested on modifying the way in which the categories display when publishing, because when you have many (like myself) it becomes quite complicated.

We require that the deployment of categories for a publication becomes a dependent listbox and then this listbox generates another listbox until the end of the last category ....

something that kind of looks like this, but with a listbox to the images attached ...

If you, or your team and / or company can do this pleaase answer this publication, in order to make a contact and work on details of delivery and price.

thank you very much.
