Help new savannah monitor arrived via mail sick

[azcards11]

So 3 days ago i order a med size savy from backwater reptiles as i had one in the past and couldn't find one in my area GA. He arrived and as i was un bagging him he was pretty lethargic not really moving have i had not used a Doppler to pick up his heart rate i would of barley new he was alive. I contacted them right away and the asked for a snap shot of him and i sent it and the said give him the weekend. Im a ER vet tech work mostly with small animals ,but i do have exotic exp. I have owned a savy before and currently out of the many pets i have my reptiles include a ball python and a iguana i've had both for over a year. So the day i got him i had a custom habitat i was supposed to get the night before of craigslist 6 1/2L 4w 4H ,but i got screwed over so i got a temp 100 gallon tank (i know they are terrible, but it had to do i have since got another enclosure hopefully he makes it until i pick it up. but any way as i was saying he was listed as small/med so he is a juvi ,but literally had no weight on him at all. His basking spot is steady at 125-130 hot side about range 98-102 cold side about 80 two hides and a moist box large water bowl with ramp he can soak in and just some fake plants to give him some cover. I know shipping is stressful and wouldn't be alarmed if he did't eat first day ,and he didn't was pretty lethargic all day did bask. I offered crickets and superworms first day and i have a colony of dubia going already before i got him. i also have pinkies frozen to be used PRN. last night i got off work at 4 offered roaches and worms nothing then i put the Styrofoam up to give him so privacy but left small opening to watch from distance he began trying to swallow with his mouth open almost like something was stuck in his throat then vomited a clear liquid and drank right after. I ve spent almost 1500 one supplies habitats and feeding supplies im very pissed and upset the humidity in cage is pretty steady at 60%. Kind of lost at what to do he needs to eat as i know ive only had him 3 days ,but he was already very malnourished. I can give him anything medical he needs, but there is no good exotic vet in my area the vet at my clinic has some experience and we do see exotics. Please help i know i was shipped a sick animal and just want him better. i know syringe feeding is always a last resort ,but he needs food. Any advice would be great and if he doesn't make it any one can recommend a place that could ship me a healthy monitor?
