I see no one has replied so here are some ideas, NOTE I am a DIY person so I have no first hand experience.
1. There are several handymen on this site, hopefully one will reply.
2. ACE hardware now has a handy man option.
3. You could contact the local paint stores and see if they have any leads.
4. While there are several interior/exterior painting companies in the area, this job maybe too small for their interest, but you could try calling them.
5. The Daily Sun typically has a classified section which lists painters that you could contact.

IMHO, with a screw driver and some painters tape this is not a big project. You may actually find spray paint that would be suitable, and fast drying. I would remove the hardware, clean the door with TSP or similar, apply painters tape, and paint the door.
You did not indicate if you have a storm door or another suitable way to secure your house, so you need to figure out if you want to remove the door or have it painted in place, allowing a suitable time frame for the paint to dry before using the door.

I am hoping others with experience or other ideas respond.
