Expensive or not sharpening blades is relatively simple, whether carbide tipped or steel.
You can get a fine file or use a fine grinder. Just follow the angle and direction of the teeth. Each tooth will go at one angle the other opposite direction/angle.. This is obvious though. But what is important is to be sure you only sharpen the top edge, maintaining the angle and direction it was sharpened in the first place. Do not try and sharpen the bottom or side edge. It's tempting to try and sharpen the bottom or side edge because it can have been scratched or nicked pretty badly. However you've got to stay on the top edge attempting to maintain consistency on each tooth, filing each one down equally.
With the file or grinder sharpen toward or into the tooth. or from the direction of the side edge, into tooth verses up from back of tooth. this will cut the tooth straighter and create the sharpest edge.
Start on the right angle sharpening every other tooth, until each right angle tooth is done then sharpen the left angle so you can maintain and become used to the same angle as you move from one tooth to the next. And filing the same angle maintaining the direction and not become confused. Or left angle first then right.
While you will not get it perfect, once the top edges are sharp, it'll cut like butter.
I expect too you might be trying to push your wood threw the saw to quickly and burning your blades as this is very common.. It's when the blade gets hot that it dulls fast.
If this is what you are doing, slow down and let the saw do the work.. push it gently and especially evenly applying the same or equal pressure throughout the cut.
By doing this you will have much less blade marks in your riped angle too.
When I rip or cut anything, I try and hold my breath too, although I don't advise it. But when I do the smallest thing like breathing while cutting, the cut edge will show each breath or slightest movement i made while cutting..

I assume that you're talking about circular saw blades? If you're not interested in doing it yourself, try Doc Stanley's in Hilo. I'm not 100% sure if they do it.

I've never tried holding my breath, but I've ruined a couple sheets of plywood after a bad farting episode. It's hard to rip material and duck flying objects at the same time.

I haven't used them, but I believe there is a sharpening shop next to Dell's farm supply.
