This is my plan

I plan on finishing my studies for cyber security and networking after my 3 years but while studying I would like to start a PC building business, which I have already started doing. The business works by having the customers schedule a consult where they will tell me what they need the computer for and what kind of budget they have. Then I will order the parts through a supplier and build it. There are 2 reasons why I want to start this business. The 1st being it would be a job that I will always enjoy doing and it would also be another way of making money. The 2nd being that with most pre-built PC's you get from shops with go all out ond graphics cards and cpu's but will cheap out when it comes to motherboard and ram and if you want a pre-built that is custom, most company's will have an extreme build fee which will on average be around $800.

How will I do it?

I plan on running this business at competative price because making money is not a concern. I just want to build PC's. So I have started by making an instagram and facebook page where I will try to expand my customer base. I have been getting my nan to help me as she has a clothing business she has been running from home for a long time. So I have been promoting my page on my personal instagram and all I'm waiting for now is my first customer.
