Well I don't charge for anything I just help where I can. As far as dieting goes what you planned out looks decent, Maybe a little shy of what you will need to get to where you want to go. Trouble is writing diet plans becomes very cookie cutter. everyone is unique. IT comes down to nutrients really. Achieving proteins, carbs and fats goals each day. Its the the theory of macronutrient base dieting. or flexible dieting.

Both are great sites to get an intro on how that all works.
It takes a little trial and error but its important you understand it cause ultimately you are in control. You want to have the knowledge to make the right choices with diet.
People often get burned out with the dull structured diets. When you focus on nutrients rather than specific food it allows you to make substitutiions and alternatives.
Also keep in mind some people respond better to certain nutrients. some need higher carbs some need to go lower. If someone writes a food specific plan it doesnt account for those little one offs.
Rather than shooting for a specific food structure shoot for this.
250-300g of protein per day
350g of carbs per day
100g of fats per day.
That equates to about 3500 calories. Should be just slightly higher than you're TDEE. Witch is good...
See how that goes for you and go from there play with upping the protien intake here and there. see what different levels do to your body specifically and find what works for you. What you need to do to get where youre going is bulk a bit. Add some weight. Its done by creating a caloric surplus. Dont get sloppy or anything. just go to surplus using clean foods.
Supplementation.
Not sure what youre taking now if anything but you of course have whey, creatine, bcaa's all helpful supplements. just remember supplement is to supplement not replace. People commonly forget that.
