Slutz come on down he just asked!
I will try to give him an answer as good as I can.
So yes 30 K for High End is a bit difficult.
Have a look at places like this and you fast recognize that 30.000.000 $ is the right investment.
But don´t worry I think you can have great sound with your 30K but may not as great as on those million dollar high end studios.
You should write a business plan before you blindly invest money.
As the others said the most money would go away for room treatment but I know many guys which have done a fair tracking room DIY with reading many books measuring and building the treatment by their self.
Investment was around 10 K and many weeks and months... hard work.
You may also can live with overdubbing and a little room for both mixing and tracking this would save you a lot of money.
But it must be said my small studio here what is mainly used for mixing is still around the 20K line.
You fast can spend 30 K and not getting what you expected.
Also do not underestimate the time to get know how.
If you cant afford an experienced engineer it would take 4-6 years to learn.
This is the time you need to get fair results in mixing and recording. So here is my advise for you.
I first would think about the whole investment because many major labels closed their in-house-studios in the last 10-20 yrs.
The reason is clear such a Studio is not a money maker.
So I would calculate what is giving you more gain for your business. Hiring a professional Studio or building your own one.
If you hire a studio it do not have to be High End to get professional records.
You also can live with smaller places which also have a good tracking room which sounds great.
Many studios have nice consoles and they cost you about 500$ a day with engineer!
This means 7 days tracking would be 3,5 K for you.
In the meantime the rest of your money can work on the bank at maybe 6% interest for you.
Mixing by a professional which may mixes ITB (which is may not a big time mixer) but someone who makes fair mixes for fair money would may cost you 150-400$ per Song. It depends on how you comunicate with the enginner and also how much work the diffrent songs will cause mixing them.
So in the meantime your band can sell albums for your label.
You make money and you can concentrate on the next album with a diffrent band. Having your own studio would mean for you.
Paying insurances for the Equipment and the Studio-building.
Paying for heating and power.
Paying rent for the studio.
Paying money for maintenance.
Paying an engineer who may will cost you a regular wage.
Judge yourself by careful calculating.
I bet you can save a lot of money and a lot of stress by doing the tracking and mixing at existing professional places.
All the best...
