Washing and ironing curtains

TLDR Will an iron press work well for ironing/pressing curtains? Will it work fast and will the result be good?

MORE DETAIL AND CONTEXT:

I have 4 linen curtains that sit in my dining room. I have cats and a toddler and within 2 years these curtains are in dire need of a good wash.

My trouble is the ironing. The took about 2-3 hours each to iron last time I put them up. I called around to ask for pressing or ironing service and I got quotes ranging from $40-$85 per curtain, so a total of $160-$340.

I found an singer iron press that costs $160 thinking it will take a lot less to use a press instead of an iron as spending $200 every couple of years is a bit too much for my household.

So, do I buy this?
