Publications... Im a beginner

Hi people
I m just beginning with SQL Server 2005 Express Edition and I need some help.
I want to have a small database in a server (I've already created) and it will be used to synchronize it with PDAs (Pocket PC 2002) through MS SQL Server CE 2.0.
I have "SQL Server 2005 Express Edition" and "SQL Server Management Studio Express", and I don′t know how to create a publication of my database (I need a merge publication). I think it is necessary in order to make replications.
Any answer, idea or suggestion would be welcome.
Thanks in advance.
Best regards.
Ok I found this at http://msdn2.microsoft.com/en-us/library/ms165686.aspx
SQL Server Express cannot serve as a Publisher or Distributor.
I don't want to (or can not) pay a SQL Server license so... I will try to do it through web services.
ciao!
