L-1B does not impose a universal recruitment test in place of the specialized-knowledge assessment.
Spend effort on the actual standard
Budget relevant evidence preparation and confirm current charges. A costly recruiting exercise does not substitute for showing what the applicant knows and will do.
Government filing fees per the USCIS fee schedule, Form G-1055, depending on the forms and employer size, with optional faster processing at extra cost, plus professional fees and the internal hours needed to document the specialized knowledge and prepare the American position description. The larger cost in an L-1B is professional time spent turning a control-system change log and internal design notes into an explanation an adjudicator without engineering training can follow, which is where most specialized-knowledge petitions succeed or fail. When the beneficiary will be stationed primarily at an unaffiliated client site, the client must not principally control and supervise the beneficiary, and the placement must relate to a product or service requiring petitioner-specific specialized knowledge rather than labour for hire.
