Hi Tommy, good question! We struggled with pricing at the start also.
The main thing you must remember is never undervalue your work. If you have a strong body of work (which from what I have seen you do) then you can feel confident in quoting a fair yet competitive price.
We gathered day and half day rates (shoot, edit, post and travel) from local companies and freelancers and based ours on that. We never quote on under a half day rate because generally clients underestimate times e.g. setup, talent nerves etc, but if it is a fast shoot then we will invoice slightly lower. Clients love that!
As for equipment we looked at local rental companies and discounted by 20-40%.
We always quote full price for the first video, even if the client dangles the "loads more work" carrot in front of us. If they are good to work with and book more work we then give them an ongoing discount which should cement the relationship.
There is no real global price for this, you just need to look at your local market and base around that.
Hope this helps.
