Gambling Website Portal Relaunch

have a gambling portal website which I have owned for nearly 2 years. It did make some money a year back and at one time had a PR6 - it is now a PR2 mainly because I have not had time to upkeep it properly. I have decided to put some time and money into it to relaunch it. The basic design is fine so nothing needs to be altered there but I need help with a number of issues listed below: 1. new keywords chosen for the site which are not too competitive eg. not 'online casino' 2. once these have been chosen I will need full seo of the site 3. Monitoring of search engine positionings 4. link building and also search engine and directory submission 5. new articles written (this could be outsourced if need be, but would need your advice regarding keyword selection) 6. Possible a Google sitemap added - although I will go with your advice on this 7. General promotion ideas for the site Ideally you will have had experience with gambling sites in order to give the best service for a gambling affiliate payment based portal. Please apply explaining how you would help the site and the payment you would require. Also details of any previous projects of a similar nature would be useful. If needed please request the url as I don't want to place it here.
