Business strategy / marketing for a new build music recording studio in London!!

Hi! Im running a new recording studio in London. (Hackney, London Fields)
Its going well and moving slowly the right way - and as the studios are finally fully build and up and running, then I'm very interested to find a person who can advice on how to improve, grow and manage the business even better and hopefully soon be able to fill the calendar with the more professional/established artists and their labels/managers.

I have over the last two years build/ soundproofed/ designed 4 music studios.
2 rehearsal rooms and 2 small but well equipped recording studios.
Im a 31 year old drummer and producer and have been working with some great artists over the years , many of them are now also clients in the studios.

The business is:
Hiring out studios without engineer / or with an engineer
Mixing
Drumming (Live gigs and recording)
Film music
Voice overs and video related audio work.

My thoughts to where I can need help:

- Settling down more on products / pricing / concepts
- Building a creative/social community around the studios and all clients
- marketing strategy (could be something we engage someone else to do after your help if its not your thing)
- Time Management of my time and generally improve processes to allow for engaging other engineers/producers more and make use of more freelancers. Id like to get more time to actually produce / create music.
- Possibly hire staff / freelancers for various jobs.

Id like to hear your initial thoughts to these things and how you can help.
You may not be fit for everything I need , but let me know what areas you can help.

Ideally id like to work with someone who can come by and see the studios and ideally also someone with an understanding of the music industry.
However everyone with experience in the field can email me.
- I will read every email I get and will soon work with one person or maybe more who can help making winter/spring 2018 very exciting for these studios.

If you are able to do more than consulting such as hands on marketing work etc - then just let me know.

Please include your hourly rate?

Also id like to know how much consulting you suggest me for a start and how a process using you would look like.

Many thanks. Kris
