Produce a list of 100 sites for backlinking

We are working on SEO for our website which promotes our online software. It's called Better Proposals and it's an online proposal system which allows users to send out web based quotes and proposals. We are mainly targeting digital agencies such as web designers, graphic designers, social media agencies, online marketers, videographers. What I need you to do is search some of our obvious keywords in Google and make a list of 100 sites/sales blogs/design blogs that we can get in touch with to link to us. You don't need to contact any of them, just produce the list. Of course when you search, you'll find a load of our competition so please exclude these from the list. There shouldn't be any proposal software companies on the list. A few examples of these are Bidsketch, Proposable, Proposify, Pandadoc.
