Marketpress : Need Manual Payment (local bank transfer) and custom shipping rate


I wanna ask about manual payment since people in my country don’t familiar enough in buying things with credit card, or other online payment. and since marketpress doesn’t give any manual payment option, now I’m in the blank (the checkout system can’t work if I don’t choose any available payment)

need help ASAP, I know it’s simple script, you can just gimme the code and where I should put it.

also how can I make my own ‘custom shipping’ ?, it’s kinda 3 column, named “Destination”,

“price” and “additional price/kg”

e.g :

city A | $20 | $5

city B | $15 | $5

city C | $30 | $7

thanks for helping me,
