If you have any ideas can you give me some tips please. I already have a domain (www.madmania.co.uk) and a host (1and1). The purpose of the website is to make a bit of money.

Thanks

I recommend you this ideas -

A website to help track the performance of your personal stocks and shares, giving automated investment advice based on a selection of algorithms.

dont do anything with it...just sit on the domain until someone else has a real use for it and is willing to pay you for it...

...that's about all your idea is good for anyways..
