Devex’ focus is the supply of the best management and optimization tools for accessing our natural resources in a sustaintable and profitable fashion, always complying with the highest standards of ethics, social responsibility, transparency and safety.
As for most natural resources industries, the key for a successful mining operation is the continuous, pro-active management of costs, risks and uncertainties, ensuring timely delivery of the products within the specifications established by the customers. Hence, Devex responds to the daily challenges of the mining industry through establishing a partnership with its clients and focusing on the conversion of operational information into intelligence for managerial decision-making. The end-product is not only a comprehensive visibility environment for the entire mine value chain, but also a practical mechanism to allow process optimization and market-oriented mine production scheduling.
Our applications contains several images of mining equipments that we create inside the company (without a designer). We would like to improve those images because they are very simple and 'windows 3.1' style.

Our clients are the mining companies. Companies that extract natural resources like iron, gold, diamonds, etc.
Our applications controls the operation process with a central dispachter computer and on-board computers in each vehicle. We have lot of images of this vehicles (trucks, escavators, loaders, etc). Those images make easier to our clients to take decisions, for example if they saw an vehicle in red color, they automaticly knows that the vehicle is on maintenance state.

We would like images of equipments with various states like (truck in operation, truck moving, truck in maintenance, escavator in operation, escavator waiting trucks, etc). Today we have around 800 images resulting the combination of models of equipments x states.
We would like just a preview like 2 states of 2 models (truck, escavator).
The images must be in transparent GIF format with 50pixes horizontally and 35 vertically. Try to leave an space of 10 pixels on the top part of the image because we put there some small alarm icons.
