What can I do for getting a job??

Actually, I'm looking for a non-paid job because I cannot earn money according to my human resources department (I'm spending my holidays abroad)
Now, plenty of questions are invading my brain! Questions such as: where can I look up? who can advice me? or does volunteering worth?
I've been told to ask in a convent next to my place, they could be willing to "hire my servicies"
I try figuring out what I can do there but I'm not sure if I'll be useful because I am not confident of my English.
This situation stress to me a lot!!
Tomorrow I will go there!

Getting started in London

Finally, I'm going to break the ice with my first post!! I hope you enjoy it!

First of all, I would like to talk about my previous steps in London. After four days staying here I'm starting to know deeper the city. Despite of driving on the left I'm getting used to ride my hired-cycle. I didn't mention it before but in London you can hire a cycle by credit card, it costs peanuts! Here it's the website where you can check out the offers: http://www.tfl.gov.uk/roadusers/cycling/14808.aspx

Because it looks a brainstorming I'm going to put all my ideas together and I will continue later or tomorrow.

Bye^2
