Greetings from Neusol. Our Company is interested in your Gold Partnership. We have already been a Silver Partner of Microsoft. Please guide us about your procedure.
Here you can read about the journey to become Gold - https://partner.microsoft.com/en-us/membership/
In order to be highly successful I recommend that you specialized in an area and build your expertise - great guidance for how to build a specialized practice is to be found here - https://partner.microsoft.com/en-us/solutions/practice-areas
It is great to have the Gold status and that will help you in your business - but there are many that are Gold today so in order to differentiate you will benefit from being specialized in one or two areas as that will help you build even deeper knowledge and market yourself.
