Good job, Alejandro. You sound pretty comfortable speaking English and I was able to understand everything quite easily.
A couple of vocabulary corrections:
"cooks" or "chefs" ("cookers" is not a word). We can call someone a "chef" if they have a very high level of training -- either they earned a culinary degree or they completed an apprenticeship with a chef. Otherwise, "cook" will be an appropriate job title.
"I'm not very sure" (instead of "I'm not pretty sure"). The adjective "pretty" only works when making a positive statement; whenever we add the word "not" we need to use a different adjective such as "very" or "so". Examples: I am pretty happy. I am not very happy. He was pretty certain that the plane would arrive on schedule. / He was not so certain that the plane would arrive on schedule.
