Arranging Warehousing / Shipping Mainland China

We are a small company looking for warehousing. We are looking for a company or individual who can help us find reliable warehousing and shipping in Shenzhen Mainland China. Products would come from Hong Kong and mainland china. After they have been received, they need to be checked for any damages and given to the courier when they are sold. Pick ups would be from Monday to Saturday and there will be at least 1 pick up everyday. Our products require around 2m³ - 4m³ of space with the potential of growing toward christmas. We have basic requirements for processing our orders and the job is not labour intensive
