Avearge Maintance Price For 17m X 5m Pool

[ReeBkk]

First off.... sorry if there is already an answer to my question posted on here, I did search but turned up nothing...so..

I am trying to find out the average price for filling up and maintaining a pool that measures approx, 17m x 5m, with the depth ranging from 1m to 1.5m.

Right now the pool is empty and requires a new filter.

I have no idea about pools and though this might be a good place to start, I'm looking for a rough quote on:

How much for a new filter (no sure of the size, but it must of been adaqute for the size of the pool), we had previously been quote 5, 500 baht.

How much to fill the pool

How much to keep the pool clean, per month.

Thanks in advance for your help....
