Am I in too deep with my rental repair?

[Riley Holt]

So I have posted in the past regarding my rental and the issues with lead paint on the exterior. I  recently did a renovation to the garage that was right next to the house causing damage to the existing wood siding. I now have access to all the areas I need to repair but I am disheartened. What I was hoping for was a quick "scrape and paint" but since it has lead paint no one wants to mess with it. I used LP smartside on my shed (the 8" x 12' boards) and I like that and would like to put it up on the rental. I just feel like doing the work myself, which I can do, will take me 2+ months utilizing all my nights and weekends as I work full time. However, the quotes to reside and paint that I have been getting are in the ballpark of 5K-8K and I can't afford that. I feel like I got into a rental that has more issues than I can handle and any and all guidance would be greatly appreciated.
