the earnings are ok but not super duper
Then it's unrealistic to dream of a super-duper price.
It is very common for businesses to be valued by a multiple of the earnings. What figures do you come up with when you multiple the existing annual earning by two, three or four? That's probably the most realistic ballpark.
Note that earnings are what's left after expenses, and the expenses need to include a value for the time you spend working on the site.
Potential buyers will make their decisions based on net profits that can be generated, not just "buying a job".
