A review of this problem early in the planning stage is recommended. You may feel that most of the consultancy you are likely to require is available free within academia. But in more technical areas, this is less likley to be the case. Some contingency in the budget for external consultancy is therefore recommended. A shoestring budget may make your proposal look more attractive to a sponsor, but it won't make delivering on time within budget any easier.
Media costs Raw media costs are prohibitive from an educational standpoint.
Movie can be several hundred pounds a minute, and most suppliers are not willing to consider selling less than a minute at a time. Media costs will be high if they have to be purchased from commercial sources. Some suppliers are sympathetic to education, particularly if there is no financial gain involved, but many aren't. Media acquisition costs will increase if someone has to be employed to search for pictures or film clips. On top of that there are processing and insurance costs.
