Opinions are appreciated

Hi all!
I am new on web bussinesses. I created this site (http://www.sotirioutravel.gr) for a friend and got no money, since I did it mostly to exercise and test myself.

But I would like to know how much do you think my work worths, If I was to sell it.

Thanks in advance,
Martha

its nice, its clean, but the price, it depends on how long and effort it took you...in my view
