Since the Item is going to be the same all the time, you really dont need to use a recordset to look it up, you could just enter the information in the bindings panel. Actually using a recordset will just add unneeded overhead.
The error you are getting is because you are missing a closing parenthesis in the if statement:
<?php if ($stonehouse->GetTaxableTotal() >= "1000" { ?>
should be:
<?php if ($stonehouse->GetTaxableTotal() >= "1000") { ?>
