Make ready printfiles for producing logomats (longterm work collaboration)

We're selling about 14 doormats with logo, for 7 doormats we must have a ready print file to produce them. This means the designs/logo should be transformed to the correct colorscheme (e.g. 16 colors, 32 colors, full color) sizes, background color and resolutions. Exact details per different logomat will follow. Here some examples of the designs [login to view URL] [login to view URL] Workproces: we’ll send the design/ logo from our customer to you. You’ll make design and send it back to us, we’ll ask for an approval from our customer. If customer is not satisfied, we’ll send the desired changes to you, untill the customer is satisfied with the design. Logo will be adapted on an average of 2 times (changes must be done as soon as possible). Some designs will be done in 5 minutes, other will take longer We want to work with a fixed price per logo / design and when we're satisfied it will be on a long term! It would be handy if you're available at our office times (9 - 17) UTC+01:00 Amsterdam (because changes should be done as fast as possible during our office times) Please give me you best price for adapting one logo!
