You can get your own enterprise OID for free from here:

http://pen.iana.org/pen/PenApplication.page

Note that you only get one, so it's up to you to subdivide the space. 
For example: if you get 1.3.6.1.4.1.99999, then you might decide to use:

1.3.6.1.4.1.99999.1 = LDAP object classes

1.3.6.1.4.1.99999.1.1 = myMailObjectClass

1.3.6.1.4.1.99999.1.2 = someOtherObjectClass

1.3.6.1.4.1.99999.2 = LDAP attributes

1.3.6.1.4.1.99999.2.1 = mySpecialAttribute

then later you can assign under 1.3.6.1.4.1.99999.3 for something else 
that needs OIDs (e.g. SNMP MIBs) and so on.
