Northwestern Mutual.

I have several policies with them for much larger amounts than you are
searching for. My first was after my private with no increased premium.
Second and third policies were after my commercial and CFI, again, no
increased premium. The agent is the key. Make sure your agent has your
interests in mind and not his wallet. Make your agent consult with his
superiors, do not take his word. Make him do his work.

Ask him how the policy treats current activities i.e.: when the policy is
purchased VS future activities. You may find that a short flying hiatus
will put you into the "non pilot" or "no current intention to continue"
category and that you can resume flying at some point after the policy is
purchased with no effects to your coverage or premiums.
