Medication and Vitamin importation to United Arab Emirates

I would like to know detailed information about the procedure for importing medicines into Colombia. We are a company that distributes medicines and vitamins in our country, but we are looking for external suppliers that guarantee reasonable prices and excellent quality. I would appreciate it if you could send me to my email the step by step to carry out the management of the purchase of the products, delivery times, payment methods, what means of shipping they have by air, sea, which transport is more agile and which is more economical, What happens with the products that you do not have in stock, do you get them from another supplier? the price is the same? do they have discounts? How does it apply?.
I require the most information that you can provide me, it is valuable to be able to decide the opening of our new allies, hoping to have good news to start a business relationship with Colombia. I appreciate your help
I appreciate if you can send me the information to the mail
