How to monetize our site - PR5, 25K unique visits, site is 16 y/o

Hello WarriorForum ,

After reading this forum for the last couple of years we (gf and I) finally decided to buy an up-and-running website and join the forum.

Using techniques found on the net we found a website aligned with our passion and the owner agreed to sell it. The website is PR5, it has anywhere between 20 to 30K unique visits per month, has 900+ backlinks and it is approximately 16 years old.

The previous owner had done very little to monetize on it. The site contains approximately 200 HTML pages of which approximately 10 of them bring 85% of the traffic. The site ranks in the first page of google for keywords such as "all natural, MSN, cat's claw, urine therapy.." A good number of the pages content is pretty random and not aligned with those 10 pages.

I changed the design of the top 10 pages, added Amazon links and Google adsense. The site generates barely a couple hundred dollars per month mostly coming from adsense. I want to fix that!

I would like to get advice from the experienced users for the following:

- since the website is purely HTML pages. What platform should I consider using (e.g. wordpress) since I have limited programming skills?

- For the next few months we are traveling so we are thinking about keeping it as a content website but are open to the idea of drop-ship model. What online generating revenues would you suggest based on what we have described above?

- Should we remove the pages that are not aligned with the main content of the website or should we keep so that they generate traffic?

Thank you very much for your advice!
