We receive a number of requests of different kinds just like any other provider and I'd much agree that there has to be a benefit for both involved parties. However I'd add that it doesn't necessarily involve direct marketing, an example being charities and foundations or similar projects which can solidify our local presence.
This in turn allows your company to approach other companies of whom may also support the same cause with a stronger presence, especially at events organised by a said charity or foundation as well as providing an essence of giving back to the community/getting involved.
