Do I have any recourse with shoddy repairs of drywall?

The repairman gave you an estimate and you agreed to pay that amount. If the work was done in a good workmanlike manner then you owe for it. If it was done wrong, them you first should ask for the repairman to redo the bad work. If they won't, then in most states you would have the right to hire someone else to fix the work and deduct it from the first repairman's bill. But before you do that you should talk to a local Contract Law attorney near you. The law can be a little different in each state and you want to be sure that you don't make a mistake on giving notice of the work deficiency and that you give a proper notice of opportunity to repair, or you could end up worse off.

Try to work it out informally. When someone makes close to $800.00 in an hour, they usually have a bit of a fudge factor to work with...

You have more than the just the issue with shoddy repairs. Make sure that the apartment complex agrees that the repairs are sufficient before you let the contractor off the hook and pay the contractor. If the apartment complex is not satisfied with the repairs and the repairs are not good they can come after you later (most likely if you are responsible for damage to the garage in your lease agreement) or retain a portion of your security deposit to cover the cost to fix the repair. Tell the contractor that you do not believe that the repairs are adequate and what is wrong with them. If the contractor is licensed you can file a complaint with the registrar of contractors and they will send an inspector out and if the damages are deemed to be less than workmanlike repairs they will issue a corrective work order (telling the contractor to fix it). The registrar fo contractors route can take more time, you may get better results telling the contractor about your issues. If you concern is simply the costs of the repairs versus the time spent, by all means negotiate with the contractor.
