I need extreem help Options

[cjk123]

So here is the deal, i am supposed to be leaving for florida on friday. I am supposed to be driving my 1.8L eclipse down there. I didn't drive it all winter and now that i started it up I'm almost positive that my water pump is going out. But I dont know if i can fix it on my own. Every place i have called around me wants like $500 to replace it and well I dont really have that kinda money, well I do except its all the money I have to go to florida on. So I need to know how easy it is, if i could do it in a day by myself. Or if anywhere around central illinois would do it for quite a bit less, like 100-150 range.

Please help as soon as possible if you can at all.
