I pay $150 for two years of HOSTING and I use Themes I've purchased for $39/year (which are great) if i get sick of looking at my current SITES, I can change them and have 50+ to choose from.
You are paying way too much for hosting. I don't even charge near that much.
As for what to sell.....
1. How about vegetable starter plants such as tomato plants etc
2. All kinds of landscaping plants, shrubs, trees, flowers
3. Fall... Mums and pumpkins and dried corn stalks
4. Fruit and vegetables.
5. Christmas Trees
That is all I can think of at the moment.
