Question about business establishment requirements for export of used machinery.

Hi all,
Me and partner (Japanese) have registered a business and we want to export used machines from japan to southeast Asia.
We just came to know that to deal in used machines in japan, we need 古商法許可 (used items trade permit) from Japan police and the time required for acquiring this license is almost 2 months. Other than that we will need to have a actual office with our business as rentor.

We want to export machines in by the end of july and since getting used machines trade permit is not possible in this timeline, what should we do?

Is there any way where we can bypass this requirement by using some local firm, if yes, what are those firms called?

If someone who has gone through all this process can guide us, it will be very much appreciated.

We are in regular contact of JETRO and other likewise services who help the businesses. But sometimes advice from individuals are more accurate than some organisation.

Thank you in advance.
