I can construct one . I was trying to check my answers . 
 
For or the first one  I came up with 
p T T F F
q T F T F
˜p→˜q T F T T
 
the second one I came up with 
P T T F F
q T F T F 
q→˜p F T T T
 
and that the statement is equivalent. I was trying to check my work wasn't sure if I was correct

I agree with your tables. Yet they demonstrate the two are not .equivalent. The top one is T T F F while the bottom one it F T T T.
