Online business ideas

Hi

I have been interested in starting an online business, I currently work however I have a lot of spare time.

The ideas I have come up with so far:

1. Web design
I am pretty good at setting up websites, buying domains etc. Would be good idea as I do sit on a computer all day long anyway. Only problem is that there is a lot of competition, how would I make myself stand out? how would I gain business?

2. Service based website
I have an idea for a service were people pay to advertise a specific product on my website, good idea as it requires minimal effort from myself however I have a direct competitor or two. Not sure how I would make myself stand out from the competitors and how I would gain customers.

3. Homemade natural body products
I would be interested in creating my own body scrubs, packaging and selling them. The only issue is this is a over saturated market. How would I make my products different. I like the idea of Frank body scrubs, simple product however the marketing Is what makes it stand out.

These are the main ideas I can come up with, not sure how good they are, what does everyone think? Do you have any other ideas for me?
