Can you PM me more information? Im possibly interested as long as the project seems trustworthy in my eyes.
There is no more information to be given unless you are qualified to take part in the project based on your professionalism.
Sounds pretty shady. I have a wide knowledge of Bash/CLI on GNU/Linux. However since you are asking for a loan, then a contract might be the only way to go. However for such a small loan, signing the contract won't simply be like it.
I will not react to your comment, probably you are using a google translator to interpret English to your native language and vice versa otherwise you will not be talking about what is not written on this thread.
