I worked for them as a letterer at an embarrassingly low page rate. I took it to get some more superhero style stuff under my belt, hoping that I could at least use them as a springboard to get better work down the line.
For the first two books, things went ok. However, on the next four, I had to send invoices up to six times with constant reminders in order to get paid. It was crazy how often someone could "lose" invoices or have them "caught by the spam filter". After having waited about 6 months to get paid, I walked and stopped doing any work for them. They did eventually pay up, but it took a lot of effort to get them to do so.
During the above situation, someone who'd worked on one of the books that I worked on contacted me to see if I'd been paid. He'd taken a back-end deal and was told that the book hadn't made any money. I wasn't surprised, to be honest -- It didn't seem like it was going to be a big seller. The person didn't know much about how distribution worked and thought that it was a lie that Diamond was only giving about 40% of cover price, so I kind of dismissed his claims at first. Then he sent me a spreadsheet of expenses and income that he'd been sent from Bluewater and asked me to look over to see if it made sense. I was shocked to find that the cost of lettering was listed at TWICE what I was paid.
Maybe there's a logical explanation as to why the lettering cost was listed at twice what I was paid, but I can't think of what it would be. What it looks like, to me, is number fudging.
That, coupled with the problems getting paid, is enough for me to warn anyone off doing anything with them.
