Answer:
Quiero comprar recuerdos para mi mama.
Explanation:
If you take into account only the first sentence, you can use Joyas and Artesanias also as an answer.
But since in the second part of the sentence it says "buscarlos", the "los" gives you a hint that the subject in question is masculine.
The command form would be "ten" as in "tenlo" which means have it but im not sure if that is what you are looking for.
