some advice please koi pond

[jpcampbell123]

recently i have become self employed and i started a landscaping company recently got a business permit for it. recentlysomething has come up the potiental for doing a koi pond for a customer.
they already have the plastic liner its preformed like the ones you see at lowes or home depot etc. i have not took measurments of it i believe i could build a filter for it out of a plastic trash can and some lava rocks my question is how much should i charge for it? i have never done one for anyone before trying to keep it affordable for them too.


thanks,
jc

obviously include the cost of the items and i would say something like $20-25 per hour it takes to do everything.
