Pay someone to clean 2 sofas or hire a RugDoctor?

[Gentleness]

Being stingy, I'd usually go straight down the cheapest route, but I have a 5-week-old who seems to have a growth spurt every 3rd day and a 21-month-old who is very needy and I can barely keep up with general housework and ongoing decluttering. To dh's glee I have finally agreed to consider that I may need to farm this job out... But I am still not really convinced.

What kind of money should I expect to pay for 2 cream/beige fabric sofas? Both are pretty filthy but not with big tricky stains.
