Helping my friend with his exporting business

I’ve been on the field of business since my college years, now I’m handling one of the biggest shoe manufacturing company here in my country. Just yesterday, a really good friend of mine asked for my help with his exporting business. He got acquainted with this after his involvement to his foreign bride a week ago. He said they are business partners and my help would really give a big impact to his emerging plans and venture. The thing is I’m not yet exposed to this kind of platform, how could I help him. Take note, I only do local and nationwide marketing. Please help!
