How much will a diy deck cost?

We are wanting to build a deck ourselves using SpecRite 90 x 19mm Merbau Decking onto H3 timbers and wanting to know what the approx price per square metre would be? 

Will possibly be a floating deck but may be fixed unsure as waiting to hear back from landlord.

Thanks!

 Should add- this is the area we are planning to do it, unsure of measurements hence wanting to know approx price per square metre. We are hoping to be able to cement the deck in to keep it long lasting but as said earlier waiting to hear from landlord to what they would prefer
