If it is question of total station or land survey, cost will depend on whether you want form lines or contours (measured in the field). If the latter is the case I suppose meager resources of funding agency cannot meet the cost even to cover say an area of 10 km sq.

Survey of India in view of changing natural and cultural landscape is using aerial photograph to edit or make new topographic sheet with not a such precision level of contours as photogrammetric processing with your required precision cannot be met with their own meager funds.
