Shipping consulting

I am looking for a short-term consulting partner to help me with a specific shipping issue related to e-commerce and international shipping. My store has been experiencing some increased shipping costs along with delays in package delivery, and I am hoping to find someone who understands the complexities of e-commerce shipping and can help me create a solution to get my expenses and timeliness back under control. Thankfully, I'm not looking for a long-term partner; I'm just seeking help on this particular issue for a short period of time.
If you are an expert in e-commerce shipping, I would love to hear from you. I look forward to working together to successfully mitigate the current shipping problems I am facing.
