Marquee Interior Exterior

I have a client who wants her vision of her event in a marquee brought to life with all the colours and styling so she can see how it is going to look
We are using furniture from different companies so would need to work with me on whats coming from which source etc... furniture, dancefloor, bar, centrepieces, stalls etc...
I would like to be able to come back to you and change things around if client requires it. May need to be hand drawn
Thanks
