Sounds like you're in a good position to make this work then! The background you and your wife have accounts wise should be a massive help too.
Really know what you mean about not being able to deal with 9-5 office! I'd learnt a lot of different trade skills growing up, by time I was 18 I'd helped build one house and restore 4, was lucky to have been able to lean these skills off family members in the trades. I then made the mistake of listening to my dad's career advice and ended up a qualified accountant and working in audit for one of the big4 firms for 8 years. I hated everything about it and it made me really ill (although its since been very helpful as I don;t need to employ an accountant or book keeper), in the end I decided I needed to work with my hands and work for myself. Its been massively stressful, the first couple of years really were not fun at all, but I would not change it for anything in the world. Over the years it does get less stressful, you get better at sussing out what prospective clients are like (very important bit of being S.E. that only comes with time) and how to avoid most of the million and one pitfalls you're at risk of falling down and your confidence grows which helps a lot!
