Looking for an android skilled person/ a ''geek''

Hi,
I'm looking for a person who would have real skills for computer and android systems as apps as well.
A person whose job is computers or androids, or a ''geek'' with good skills.
I would need some help with my android: nexus 7 from asus(google), to check, modify eventualy delete some apps of my system that a person installed for me...without making mistakes and erasing important things.
And i would also have some specific questions about particular apps as: super SU, app quarantine, authenticator, ES explorer, kingsoft office and security/confidentiality of my datas.
If somebody has these skills, we can discuss then the conditions.

Hope somebody is skilled for!
Thanks a lot in advance,
