At the very least, they should recommend an acid neutralizer. As to the iron, treatment depends on whether it is ferric (particulate), or ferrous (dissolved). You'll need a dedicated iron/manganese removal unit. If any vendor recommends a softener for your iron removal, show them the door. A little light reading about various iron removal options:

Oxidation/Filtration:
An oxidizer such as ozone, air, or chlorine may be used to react with
the iron and force it to become particulate iron that can then be
removed via filtration. This will also remove most sulfur
compounds. A typical setup would involve the oxidizing unit, a
holding tank, then a media filter. This type of system works quite
well, but takes some expertise in sizing - you would want a water
treatment pro that you trust to help you with this option.

Oxidizing
filtration media: This type of treatment consists of a sealed tank
filled with one of several media. Water passes through and is
oxidized and filtered by the media. Most will remove sulfur compounds
as well as iron. These are relatively easy to operate and what I
would recommend for the average homeowner. There are several
different media that can be used:

Manganese
greensand: water runs through for treatment. The media must be
regenerated with potassium permanganate. Care must be taken with
dealing with potassium permanganate as it readily dies organic
material, such as your skin, a purple-brown color. Some people are
quite comfortable dealing with the chemical; others are not.

Synthetic
greensand: This is essentially the same as option (a) but consists of
a coating of greensand on a silica sand core so does not require as
much backwash flow. Service flow rate is 2 - 5 gpm/sqft. Backwash
flow rate is 12 gpm/sqft.

Birm:
This media acts as a catalyst to force oxidation of iron. While it
does not need to be regenerated, it does need fairly high dissolved
oxygen in the water. If your water does not have adequate dissolved
oxygen (and it probably doesn't since it is well water), air
injection would be necessary prior to the birm. Additionally, birm
requires a minimum pH of 6.8. Service flow rate is 3.5 - 5.0 gpm per
sqft. Backwash flow rate is 11 - 20 gpm, depending upon water
temperatures and desired bed expansion.

Pyrolox:
an ore that oxidizes then filters the iron out. It does not need
regeneration, but needs to be backwashed (to rinse out the iron) at a
high rate. pH range is 6.5 - 9.0. This type of filter works very
well, but backwash is critical. Service flow rate is 5 gpm/sqft.
Backwash is 25-30 gpm/sqft. Backwash daily.

Terminox:
Similar to Pyrolox, but a proprietary formula . It does not require
as much backwash flow rate and is more resistance to a low pH. The
particulars are only available from the company that sells it - this
means you have to rely entirely on the vendor for proper sizing.
Backwash daily.

Filox:
Also similar to Pyrolox. pH range 5.0 - 9.0. Backwash flow 12-15
gpm/sqft. Service flow 6 gpm/sqft. It must be backwashed daily.

Pro-OX:
Essentially the same as the previous three. Requires 12-15 gpm/sqft
backwash. As with Terminox, specs are lacking information so you'll
have no way of knowing if the unit you get is sized appropriately.

Katalox-light:
Similar in action to the previous four, but is comprised of zeolite,
manganese dioxide and hydrated lime. It should be designed for 6 -
12 gpm/sqft service flow atnd 8 - 10 gpm/sqft backwash. For well
water, it's a good option as it requires lower backwash.

In
all cases, media ought to be replace somewhere between 5 - 10 years.
If any vendor tells you their media lasts forever, walk away - they
aren't trustworthy.
