I don't want you to pay me, but I will give you some advice.
Try to take your melody notes, and fit them into chords based on how you want it to feel. Tonal things generally move in ascending/descending 5ths (or 4ths, which is essentially the same thing) or steps. Sometimes they move in 3rds, but that's more commonplace of modern music. The V-I is a very powerful thing, use it. The iii - vi - ii - V7 - I is really powerful too, though you might want to use alterations or extensions.
Also, take pieces you love and study the chord progressions. After a while, you get really good at it.
