Hey Syria.man , let me say it clearly you cannot make 0.3 bitcoins in a week as a newbie or without risks , o without working hard for it..
What i suggest you to do is to go out and work hard a week for your FIAT , and exchange it to bitcoins
there is milion ways you can make 0.3 a week , you can search on your house for stuff you can sell for bitcoins
if you are a desgin , programmer or anything else you have skills on , go offer that in forum  - https://bitcointalk.org/index.php?board=52.0
Also You can make 0.0026 bitcoins a day by posting 20 HQ posts by joining a signature campaign ( im using yobit which gives you 0.00013 bitcoins per post as a member) , about the sig , for first step you need to know that you dont post junk in forum , such as this thread , beside asking us ways to earn 0.3 bitcoin , you can make a research without posting a thread as many newbies does,
use your mind and brain to make money , thats the way to make 0.3 a week.
