Part of the issue with next generation genome-level sequencing projects in a lab is finding the sequencing service provider. The prices can vary by quite a bit and a lot of word of mouth and point-to-point communication goes around, which can take some time.
I just learned about genohub where you can fill out a form for your sequencing project (here is just a random example).
Then click find and it returns information about different sequencing centers (these are just examples, not endorsements).
That combination is expensive. Here is the result of another search for 20X sequencing of a genome 450 Mbp in size.
The cheapest ones are all single reads, but you can scroll down for paired end sequencing for genomes with a lot of repetitive elements.
