Needing Your Best Advice

[NeedToKnowMore]

i'm hoping to sell PRINTS of my Landscapes and Flowers. 16x20's to 40x60's using an old Epson 9800

any links in your  answers would be most welcomed.

my thinking is only one paper is needed to sell to galleries or large homes. i picked Epson UltraSmooth Fine Art Paper - is there a better paper? (no B&W's)

what's the best way to ship when i have backing on them?
what kind of paper do i use between them when shipping?

do i need to coat them if they are not going to use glass? (i say this because there is one place i will be approaching sells photos without glass.)

anything else i need to know? please comment. i need all the help i can get.

being my 1st post and not sure how fast one gets replies. please give me time to respond. i'll check in every few hours for the next 3 or 4 days.
