modify layout point of sale software windows java

change sales panel the codes remain the same. only the layout( buttons colors ...)
attached the source code. before making an offer. open the source code and see how many panels there are to change.
examples are also added here. BEFORE and how it should be AFTER.
don't ask what my budget is. calculate what the work will cost
and I select the bid that matches what I expect.
Before that
I will ask if you are going to send images if you could open the source code.
to see if you could open and see the all panels.

is a windows application
in attachement source and installer test jar
thx
