Synthetic Thread import companies and synthetic thread import trade opportunity

I introduce myself to everyone with the interest of forming a new business selling crochet products in Uruguay, of the highest quality. The business plan is underway but the product to be sold has not yet reached the levels of excellence offered by regional suppliers. I am interested in cotton and synthetic blend threads, 50 and 100 grams, of different thicknesses. I'm also interested in the eco-friendly synthetic mesh blend known as T-shit Yarn or in eco-friendly yarn blends. I would like to know your proposals and products and move forward to find out the ideal supplier for my project. From already thank you very much.
