1KW DC to AC Pure Sine Wave Power inverter

Hello,
I want to design and build a power inverter. I have a 48 VDC source and I want an output of 110 VAC 60 Hz. The maximum power rating of the inverter is 1KW.
I'm lost between the output wave forms! Should I design a modified sine wave or a pure sine wave inverter!
I prefer to design and build a pure sine wave but I'm not sure how easy or hard would that be!
Well as my nickname says! I'm Learning and I really haven't built any power electronics circuits, so I'm kind of lost. I'm not sure how to start or where to start from, and I only have 2 months left before I finish this project!
Do you have any experience!? Can you put me on the right track!? Can you provide me with any link where I could learn more about the process and the inverter!?
Thank you for reading this Post and Thank you for thinking about an answer! I really appreciate you.
