For the most part, I can see a fair 10% increase, that’s normal and in line with the market place.

I don't want to be at a cocktail party 20 years from now talking about I wish I never sold.Frank

It is the other party that cannot enforce them though. 

Make sure that documents are signed by both parties. 3.

I would ask for a commitment from all parties involved to strive to that end.

Listing agent said another party offered $10k cash.

They hire a 3rd party company (homewisedocs) to handle the document ordering (status letters, condo certs, etc.) which drives the price upward.

I would prefer to have it done professionally, however since we are a small start up, capital is key right now and I keep thinking that we might be better served spending the additional $750 elsewhere.Am I being unwise to consider doing it myself, especially since other parties will be involved or is it not that big of a deal to do it on my own?

The remediation company will not give an absolute move out recommendation, because they refer to a third party company for environmental assessment (minimum 300-1200 not covered by insurance), but the tech has indicated it would be a good idea for them to move out for 5-7 days.  

But assuming that once you file it is a quick process of a couple days then it seems it's just an attempt at being equitable to all parties involved....especially the one that is "losing" on the deal.
