I didnt see anything about subdomains, I gotta have subdomains for my sites, so I wouldnt go with you. Also you only offer 2 ftp accounts with your platinum plus. You should get at least one more hosting plan to offer, having only two doesnt offer too much.
As for the prices, they are pretty good for what you offer.
Do not try and compete on price with other hosting companies...
You should focus on a market, so design your packages based on the sort of clients you want to attract.. Somebody has already mentioned the packages are unbalanced - forget about price and restructure your packages.. then think of the appropriate pricing once you are happy with these packages..
