Help for charity wordpress site set up

Hello Dear PW developer,

I have an unusual question perhaps, but perhaps someone can help. A friend of mine and I want to start a charity for enviromental cause to educate people – it is very unique and we want to role it out about whole britain. All will be webbased, this is the idea so far.

We talked to different people and every recommended wordpress, particularily as we want volunteers to add their own content, as there seems to be a plug in for this.
A friend of us would design the wordpress theme in photoshop. but we understand now, that we also need a person who knows how to install the wp prorgamme and the plug ins. Ideally how to modify some content, but this is not the most important, perhaps we can do this when we fundraised some money, but we need to get for this our website up and running.

We dont have much money, but we could put each 50 POunds in the pot for time someone would invest..

As a return, we can offer to very visible display name and contact details all over the website and mentioned that you helped this charity to start. As I said, it should be a nationwide charity that touches popular need for helping other.
2. When funding is available, we would need someone to look and maintain the website, we could then offer a paid as you work job.

If someone would be interesting to help, we would be so happy. if you are interested in nature and dislike chemicals and pesticides you might be very interested to work for our project, it is really for a very good cause that concerns all of us…

I look forward to hearing from anyone
