Landscaping Advice

[sillbeers15 7]

I'm at the end of my Recon for my 4000sqft. Semi D, looking at doing up the landscape now. The front, side and rear turf area combined is approx. 2000sqft with a mature frangipani trees which my builders managed to preserve for me going through the year long recon.

I'm looking at getting trees (more frangipanis and others) and plants to complete the garden.

Anyone to recommend me source to buy plants and trees at reasonable price locally?

Has anyone with successful purchase or engaging landscape service from across the cross way to share?

Thanks in advance.
