Digital Timers to control 4 relays

I need 4 timers to control 4 relays. The timing diagram is attached. Each line should be able to source [url removed, login to view] current when high to drive the relay. These 4 timers need to operate in a synchronous manner.

There is one section which requires an ability to be varied from 60 to 150 seconds. If this is too much to be achieved, this interval can be fixed at 120 seconds.

This is a fairly simple project and I assume an electronics engineering student should be able to accomplish this.

The project requirement is fairly urgent.

The project requires that a working product where all the components are soldered on a PCB or all components are assembled and working on a bread board.

The cost of the project would include all the cost of the components as well as shipping the final product to the US by a traceable means and within 3-4 days shipping time.

My preference would be to pay all the cost of the components and shipping at actuals and the cost of the bid is the cost your time and effort.

But I am flexible and may also accept reasonable all inclusive bids.

Please specify clearly whether your bid is an all inclusive or time and material bid.

Added additional categories to this listing.

The component being developed is part of a larger project that is being prototyped. The accuracy of the timing is required upto +/- 1 seconds per time slot (i.e. 59 - 61 for a 60 second time period). The objective is to keep the cost optimum and have the accuracy only to the level required for the purpose of this component.

The deliverables for the project include the following:
1. A schematic circuit diagram of the developed component
2. Listing of all the components required along with their specification
- Delivery of the diagram and component list will constitute 50% milestone for the project.
3. The entire component developed, TESTED and working as per agreed upon specifications. The assembly can be on PCB or breadboard. The following items are not included in the delivery: 5V Power Supply for powering this circuit, relays.
The delivery of the item in point 3 will constitute the completion of the project (100% milestone achieved).
