Converting an Audi A2 to electric

Ever since I bought my last car I've said "My next car will be an electric". But, I've never found an electric car that suits my budget and my other needs of a car. It has to be able to transport me and my family, which is three humans and two dogs, 60 km everyday to and from work.
So, instead I'm planning to convert a 2004 Audi A2 to electric.
I have been studying EV conversions since before summer and trying to figure out how to do it. I guess I'm not all there, but some things are getting clearer.
First, a donor car. I have decided to convert a 2004 Audi A2. Its a small, but roomy car that Audi manufactured between 1999 and 2005. It will just about house the family. It is small and light, mainly because it is built from aluminium which means that it will not rust so bad.
I just bought the car last week and here is a picture of it.

Maybe I'll paint it when it's finished so it will look prettier.
