Help selling my websites

Hi Everyone,

This is my first post and I need your help and advice.
I have 5 websites that I wish to sell. They are flower sites
and I have had them for around 10 years, and when I first had
them I was making around $20k per year with very little work.
With increasing competition the revenue has dropped
to around $7k per year and it's time to move onto something
different and to sell them.

I have existing florists who receive the orders from my sites and they
pay me a 20% commission on the orders. They all have their own sites
and my sites are just a another source of revenue for the.
I have all the sites running on the same database and to sell them I have
new individual sites made in Joomala for them ready to go when they sell.

I plan to offer the sites to the current florists and need to work out a plan
of how to make a fair offer to them. I have the revenues from the last 3/4
years to given them although they know how much they make anyway I
guess.
So what do you think I need to do to make a fair offer to them.
Your help and advice would be very appreciated.

God Bless
