The US tycoon has called in The Policy Partnership amid mounting opposition from environmental campaigners who are concerned that the development would kill off local wildlife.
The Trump Organization wants planning permission to build two golf courses at Menie, part of which is designated a Site of Special Scientific Interest.
With Aberdeenshire Cou-ncil due to vote on the planned development in October, The Policy Partnership will argue that the construction alone could support more than 6,200 new jobs.
The public affairs agency will also emphasise that the development, the biggest golfing complex yet proposed in Europe, will offer a links course capable of hosting major championships and a five-star hotel.
The main PR challenge will be fending off concerns about potential threats to local wildlife.
Last week, Scottish Natural Heritage said it would uphold an objection to the development that it lodged earlier this year – despite recent amendments to the original proposals.
David Bale, Grampian area manager at Scottish Natural Heritage, said: ‘This site at Menie is part of the largest dune system in Scotland.
‘As the development would cause significant damage to the Site of Special Scientific Interest, we have maintained our objection to this part of the proposal.
‘We are still clear that building the championship golf course on the site will inevitably damage it.’
Simon Petar, associate at The Policy Partnership, said: ‘The Trump Organization is very keen to work with the local community to ensure they support the plans for the golf courses.’
