Vitamins and Supplements

Here is a dilemma I am having.

I have chosen the niche of vitamins and supplements. I have further decided to focus on products that improve memory and concentration.

Here is my dilemma - there are about 30 to 60 products that fall into this category. They are priced anywhere from $10 to $60 for each product. If I focus in on one product, then the returns are going to be too small to justify the returns. If I focus on 60 products, the that is too broad for me to have any effect in the market (and also I might as well be a merchant at that point).

Also the vitamin and supplement keyword are very competitive.

So what are my options here?

1) I could do a review/comparison site of 3 to 5 top products, all of which I will gain a commission on.

2) I could create individual landing pages for a few top items. This would be the easiest for me, but then how would I set it up to cross-sell them other items to boost my return. Possibly capture email, etc for a follow-up email with further marketing messages?

3) I could have all 60 items in my catalog. Use data feeds to populate my pages and link directly to the merchants shopping cart. This would be very technically challenging for me.

4) I could become a merchant myself with private label products. Don't want to take that step before I have a much better idea of the online market place.

For everyone's information, I am aware of the marketing restrictions (imposed by the FDA) on vitamins and supplements and I am comfortable with them. So that is not a problem for me.

I am considering becoming an affiliate for Vitamin Shoppe and Swansen Vitamins, both of which are with CJ.

I have extensively gone over both of their websites. VS is very conservative in their marketing messages and would benefit most from a pre-sell. Swansen has better marketing. Both pay similar amounts for the sales.

Any ideas on to handle the quantity/price issue are appreciated.
