Five articles on gold trading

I need five articles of 600-1000 words each on the topic of investing in gold. Each article is to cover a subtopic such as :

- Investing in gold through ETFs
- Buying gold coins from a jeweller
- Trading gold online
- Spread betting on the value of gold
- Buying gold jewellery as an investment

(Final topics to be confirmed)

The articles should be aimed at the interested, educated reader who has little specific knowledge on investing in gold (similar style to an article in a weekend broadsheet newspaper).

Each article should give a little background, a few tips or potential gotchas and an encouragement to find out more. It is not necessary to give general advice on the risks of investments as this will be added separately but discussion of the relative risk of different investment routes should be included eg spread betting is more risky than buying jewellery.
