Easy $! Mobile Veterinary Clinic needs professional logo

Still deciding: MobileVCSU --OR-- goVET.net

I am the IT admin for a new mobile Veterinary practice. I have some very limited design skills which I used to create the comps for this logo, but I definitely need a pro at this point to give the owner a more polished answer. The practice is basically a full Veterinary clinic on wheels and is unique in that it also has a surgical suite (not many mobile clinics do surgery). The owner/veterinarian is brilliant and traditional and has the highest standards of care for her larger client base. She is looking for a professional and memorable identity for her new business.

The logo will be a fixture for the hundreds of clients of the veterinary practice. It will show up on website where they schedule appointments, as a huge decal on the actual mobile clinic vehicle (giant RV-type truck), the uniforms of the technicians, and the newsletters, business cards, and invoices they receive. It will be used consistently throughout the clinic and should be memorable, serious, and professional.

Requirements are simple, but we are very open to creative interpretation.

Name:
The name will most likely be "MobileVCSU", but we are also considering "goVET" or "goVET.net" - feel free to try either one. We might be convinced on goVET if the logo is great.

Tagline:
The tagline should be: "Mobile Veterinary Clinic and Surgical Unit" (hence the VCSU) and should definitely appear along with the logo.

Orientation:
The name and tagline should both come along with the logo. We would like to be able to show the name/tagline either underneath or to the right of the logo, depending on the usage so please make it portable. For example, we might use the logo+name/tagline underneath for the website, but logo+name/tagline to the right on the truck or shirts.

Fonts:
Prefer sans serif fonts; specifically Eurostile is nice; 100% open to alternatives.

Logo:
The owner drew a sketch of a cross (ala medical) with silhouettes of a dog and cat overlaid. This is simple and nice and something that includes this concept is likely to be chosen. She is open to other ideas.

Colors:
She is a fan of Hunter green. A nice palette of shades of green for the logo + black for the name is preferred. She finds red stressful so please avoid it.

Please AVOID:
-The color RED
-Cartoony or manga style logos
-Birds, snakes, horses, other farm animals - stick to dogs & cats.

Please include Photoshop PSD.
