Help Ariel, an Ecuadorian university student!

Hello! My name is Ariel Saltos, I am 23 years old and I live in Quito, Ecuador. I am currently studying at the EPN university studying Applied Mathematics and I am about to finish the 4th semester.

I would like you to please help me with certain economic problems I have, that's why I put the $800 as a reference:

1) I would like to buy a printer to be more prepared and equipped for the next semester. I don't live with my parents, having a printer at home is a tool that can get a college student out of trouble in many situations, and well my parents don't have enough money to buy me one either.

2) I would like to change my phone because the one I have is defective because it went through a repair process where the plate had to be changed (a key part of the phone), I was almost two months without it and as I do not have enough money to buy a new one I only had enough to repair the one I already had; however it is not like before and I would like to have a phone in good condition for the semester that is about to begin.

3) I want to send my laptop for maintenance and an internal cleaning, because lately it has been showing blue screens on some occasions and it restarts. I think it is because it is overheating a lot and I do not want the problem to become bigger.

4) I would like to have a small initial amount for the next semester for any setback that comes my way, in fact most likely I will have to pay second tuition for a subject in which I have not done well this semester. And well, in the weeks of vacation I have from the U I will work, but I don't think I will be able to cover all the needs I have, because there are other personal matters too, but that is secondary at the moment. As a form of gratitude I thought of giving my green pen as a gift to anyone who could help me, this pen has been with me for years, since I was in high school. It can be seen as a symbol of all the effort and dedication I have put into my studies throughout my life. It is not completely worn out yet because green is not a color that is used much for writing actually, but as you can see in the picture it is already quite worn out.

If more information is needed I am not sure how to get it across, it is the first time I use a platform like this, but I remain open to any indication, comment or suggestion out there.  

Thank you very much! 

Ariel
