No. 003, slowking - give the kings rock your seadra is holding to a slowpoke and trade evolve it.
No. 005, Lopunny - just evolve your buneary? It's a happiness evolution. Take it camping, play with it till you cant anymore and then cook for it (a milcery class dish, I usually use fancy apple with a pecha berry, make sure you dont burn it). level up once. Then repeat. I usualy get my happines evolutions in a few levels this way.
No. 024 Talonflame - Evolve fletchfinder at level 35.
No. 186 Larvesta - Seeing how Volcarona isn't on your list, easiest would be breeding it with a ditto to get a Larvesta.
No. 200 Kingdra - Switch the King's rock with a Dragon Scale and trade evolve it.
No. 121 Heracross & No. 194 Skrelp - These are the only version eclusives in your list. I actually got some leftovers of these lying around that I can trade you.
Can also help with the 2 trade evos if you put the proper items on them. The rest you should honestly be able to do yourself, they're not very hard.
