Short answer: IF you want someone that is competent in TN, try Dean's Gun Restorations in Caryville, TN.
https://www.dgrguns.com/ He is one of the few that has direct links on the CMP website for installing barrels to old U.S. milsurps. It will cost as time is money. I believe that he can restock the rifle for you as well but you would need to call him to find out. He would also probably steer you onto someone else competent if he no longer hot blues guns.
Long answer:
The major thing to ask your friend is whether he wants a shooter or a restoration. A restoration requires doing a bit of research to figure out when the rifle was originally issued and what parts were used. This often takes time. Some of my restorations have taken several years to find the right parts in good condition for a decent price. Thus, putting a stamped part on a firearm that originally had milled fittings is inappropriate and hot bluing a parkerized rifle will reduce the value even if you spend the money to polish out the etching from the parkerizing. Others simply go for the typical "mutt" arsenal look where the U.S. military cared about function and did not particularly care whether the fittings matched, whether some parts were parkerized or not, etc. These types of restorations are often worth less the sum of the parts because they don't look pretty. Doing non-milspec things like tapping the receiver for a scope or putting commercial front sights will really hurt the restored value as well because you have neither a sporter nor a restored rifle.
From the pictures, I can't tell if you have an 03a3 WWII vintage receiver (it will have a peep sight over the receiver bridge at the rear) or and it appears that you have a 1903 barrel where the sight base is long gone but I could be wrong. The easy tell is that WWII era 1903's and 03a3's were marked Remington or Smith and Corona on the receiver. Older ones are springfield or rock island marked.
You have a milled trigger guard which was original 03 type but can be found on all makes as they are slightly more accurate allegedly than the stamped ones.
I have restored both an 03 and an 03a3 and it costs about what the rifles currently sell for with myself doing most of the work. After restoration, figure on a restoration of about $700-800 for a 03a3 Remington if done right (slight price premium for Smith Coronas due to scarcity but parts cost more or if you have the holy grail an A4 receiver (lettering is upside down for sniper use) and a bit more for the 03 $900-1000 (leaving aside things like built during WWI, national match, rock island arsenal, hoffer thompson conversions, Mark I receivers, and the like. The 03 restorations will bring less if they are low numbered receivers--see the CMP about the low numbered receiver issue (too long to go into here). Sporters, even quite nice ones are all over the place from $400 on up.
Restorations are getting more and more difficult to find parts and the parts are becoming increasingly expensive. I did it because I learn something about each weapon and I like to shoot mine. IF you are doing to make a rifle more collectible to bring a higher price, you probably would do better buying the collectible in the first place with authentication. A restoration will always be worth significantly less on the market and you will often be upside down for a while with the restoration costing more than the rifle is worth. A pristine unfired 03 is a safe queen for good reason as every year fewer exist and scarcity drives the price up. Restorations will go up in value gradually but not as much nor as fast as you are not quite a collectible such as a worn untouched firearm but not a sporter either (tapped with a good hunting stock etc. ). Don't do a restoration to make money in most cases, do it because you love the history of these grand old firearms and want it preserved for future generations.
