You have to calculate the cost by urself. I cannot give u an estimate.
For easing ur rigidity, take this example.
I want to build a shed in Arc model with bamboo. Dimensions are 20x20.
I will use 6 side posts on both sides and 4 posts in the middle. These posts will be jam oil wood or subabul which ever is cheap. OK.
Now this shed is a square one. North facing will be good for this shed. So lower ends will east-west.
On the east side 6 side posts will come and minimum one bamboo for every foot lenght. So I will require nearly 20-24 bamboos for each side. round it to 50 for both sides. Now for vertical support there should be one bamboo for every 2 feet. for one side it will 5, for both sides 10. If you want extra support to the shed you can add some more bamboos and support posts to ensure the safety and durability of the shed.
There were other options, but if u choose Arc model, bamboo is cheap and best. If u decide on model then I can suggest something.
Shadenet will be Rs.20-25 per sq mtr, 50% or 60% is enough. Calculate as accorded with ur dimensions.
You said multi purpose, what are ur other purposes?
I dont suggest one single shed in whole 25 cents. Go for multiple sheds instead.
If you can afford to go for professional help and consultancy, go for it for one shed in 25-50 cents.
All my suggestions are my personal experiences only, act accordingly.
