Make enquiries at your local tile shop to find out who the main tiling contractors in your area then give them a call. 60 days payment terms for subbying sounds a bit long in my experience , but then I might just be lucky . Never waited longer than a week for my 2 main contractors to pay me.
Also ask if they supply spacers etc , some do some don't.
Also find out how far you have to travel to pick up tiles and snot or is delivered to site.
I've recently changed contractors to get more local work ( health reasons ) , and everything I need is in a 10 mile radius , suits me down to the ground. Pays within 2 or 3 days too.
Just to add , if it's just wall tiling then my Dewalt with 3 batteries does the day , usually only a handful of copper tails to drill for. If its flooring ( say over 10m² )then its power tools ( 110v ) , transformer if power , if not , then its get the genny out time.
Little tip as well , keep some adhesive lids ( i'm supplied with Biscem showerproof ) , and take your own water , saves sooooooooo much time when you get to site. For me 2 buckets fills my washboy , mixes my grout and leaves enough in bucket for washing off.
