what i need for my current project is, 4 temp sensors, where the temps are displays in a 4 line illuminated screen. then one of the sensors controls a fan, so when a set temp is reached a fan turns on.any comments or help welcome.couldnt find a section on the forum where you can request to pay people to undertake projects for you, so hoping this section is right

You should also explain the scope of what this person you're hiring is doing. Are they assembling everything and shipping it to you? Have you picked out the hardware, and have the basics working and just need the program written? Should they walk you though purchasing and hooking up the hardware yourself? Should they be nearby to help you get it working? Etc.
4 line illuminated screen.
A couple more clariyfing questions:Quote4 line illuminated screen.When you say "illuminated screen", are you talking about something like this: Does it have to be 4 lines?Does the project need to be put into a case?What kind of fan is it controlling?
It sounds as if you want a thermostat and some thermometer displays. Do you specifically need to make these yourself (are they a product you plan to sell)? I'd have thought that the functionality you're asking for could be obtained quite easily using standard off-the-shelf consumer products, if you aren't set on building your own.
Questions asked so far:1. Does it have to be 4 lines?2. Does the project need to be put into a case?3. What kind of fan is it controlling?To add to that:4. Does it have to be an LCD at all or could it be 4 of these:5. How is the target temperature set? Two buttons (+/-) enough or is a more elaborate user interaction required?6. Just one relay?7. What's the temperature range?Cost wise I'd budget somewhere around this:- Controller (Probably ATMega328p ~$5- Sensors 4x $2.50 = $10- Relay $5- Display $10-$50 depending on size/type- Misc items (voltage regulator etc.) ~$10======$40-$80 depending on display
So the circuitry can be attached to the case, next to the LCD readout?How far will these temperature sensors be placed in relation to the LCD/Circuit board?
