It's always the best to get your hands dirty and do the job yourself but there are many BUTS :)

You really are lucky with the space that you have and how skilled you are. It doesn't look difficult when you show it but I can imagine that when you do it for the first time and you are completely inexperienced it might be a little struggle. I'm sure that the cost of the purchases that you have to make and the time that you have to invest in the beginning will be quickly returned and long term you will 'profit'.

I hope you inspire people who have the facilities and necessary tools to do it themselves instead of spending money and paying somebody for this service.

Have a nice day!
