I want to find a company specializing in customs clearance for my goods in Cairo -- 2

I have some goods: wireless headphones and pliers, fashion goods... ship from China to Cairo via air, I need a company that can handle customs to clear my goods, If the price is good and the time is fast, I will work for a long time
I need to pay attention to a few issues as follows:
1. Clearance costs (all costs if any)
2. Customs clearance time from arrival in Cairo
