Transparency and openness is at the heart of our client relationships. We are always happy to discuss which of our fee structure options work best for you. Security requirements differ between our clients: most often we work on a fee per project basis, but some clients prefer to have us on a retainer to ensure we are available to them if and when they need us. We also provide analytical product packages for some clients and they pay according to the package they select. Please contact us on email@example.com to discuss.
