Okay thats kind of good, but i need the price for the hub itself.

If you buy a front hub odds are the spoke lengths you will need will not match what you have currently.  It'd be a long shot for a front hub to have the same flange diameter AND the same flange->center measurements.   But it does look like that hub has no dish so at least you don't have to worry about the spokes being shorter on the drive side than the non-drive side due to it being a flip-flop.

If you DO ahead and do this and re-use the spokes make sure that you keep the inner and outer spokes segregated when you disassemble and be careful to get them back into the same position (inner/outer) on the new hub. The heads are bent at different angles and if you mix and match them this is going to cause all sorts of issues in the future with tension/true.  

For the work, the cost of a new hub, plus the many new spokes if these won't fit, you are going to be in the hole over buying a whole new pre-built wheel most times doing something like this.  The used hub isn't going to net you anything on the used market -not even the price of a new front hub I wouldn't think unless you were downgrading on it.  If you have never built a wheel yourself be prepared for the first one you do really sucking and having issues sooner rather than later.  

But if you really want to do it then go ahead.  You might enjoy it.   If I were you I'd pick up a junk wheel from working bikes and tear it apart and rebuild it a few times to get some experience first.   And there is always Sheldon's required homework reading.

James thank you for the information. I was considering recycling the spokes, but how would I take them off? I still need to find that front hub of the same make. I dont get what you meant by the third paragraph when youre talking about the used market. Please explain

You take the spokes off just like you put them in -only in reverse.

By the used market I mean selling the rear hub on Craigslist or other website like here.    There really is no real reason to buy the same brand name front hub unless you care about matching. Even if you get the same brand/model of front hub it probably won't be the same size flange diameter or distance apart.     -you can find other hubs in that color I am sure. 

By the time you buy a new hub and spokes it'll cost as much as a complete built-up wheel.  They sell wheels for much less than the sum of all the parts they are made out of at the prices ordinary folks like us can buy them for.   The wheel manufacturers buy hubs, spokes, nipples, & rims in bulk and pay less than half of what we do.  Then they lace them on machines in china where the labor cost to run them is less than the shipping to bring the wheels here.

Sigh... OR! I could order a custom wheel set and keep the front and sell the two rear ones for an okay price, so that I break even or lose like 20$. Or i could return the two rears saying they sent me the wrong stuff and ask for refund. Lol tell me what you would recommend because Im basically using a rear wheel as my front

Is that bad?

A new hub is going to cost you $20 and a spoke set is probably going to probably be well over that again -especially in red.

So i figured Im not going to relace it. I might just keep it, but Im wondering if its okay that i have a rear as a front. I did remove a bolt from each side because the axle didnt fit into the drop out, it was too wide, so to make space i removed a nut. do you know what i mean?

Those nuts you removed are the locknuts that keep the bearing cone nuts locked in place in the right location.  Now there is nothing to keep them from moving in or out except the tension of the outer nut against the fork drop-out.   Most likely, unless this is a sealed-bearing hub, your bearings are going to either get too tight or too loose as you ride.  

Those nuts are there for a reason -nut just as spacers.  If it is a cartridge-bearing hub it probably doesn't have a second set of nuts so I'm going to assume this is a loose-bearing type hub.

It is sealed, I tightened those nuts not too much but enough so that I couldnt loosen with my hand
