Who can develop the following Python script into working application ?

[http://members.lycos.co.uk/dariusjack/]

Hi,

I am happy user of Nokia 770 tablett
and one application for  Nokia 770 is maemo mapper (beta navigation
application).
And the following script should run under mm (for Debian).
Its developer told me it wans intended for other developers.
I have no idea how to write Python script
so please tell me how to learn how the following script works and how
to modify it to be fully working,
Frankly speaking I would prefer to pay for your kind assistance
as it may take me to much time to learn some Python and understand the
following script.

I would like to modify it to add 2 more columns to SQL (sqlite3) POI
database, to set proximity value and spead limit as in safety cam POI
in standard car navigation systems.

Please let me know your opinion.

Darius
